I've posted in your tank thread now ;)

What dosage are you using and what tank size. Are all the ingredients in your solution dissolved? Is this freshly made with the whole packet being mixed with 1litre or are you making up smaller amounts not using the whole packet?

So did 4 trials: A Tap water + EDDHA + Phos B Tap water + DTPA + Phos C DI water + EDDHA + Phos D DI water + DTPA + Phos. My tap water is good old Lincolnshire Jurassic Ridge water. 19KH!!! A showed the reaction as described earlier within a couple of hours B showed no reaction to date (5...

I'm running a test at the moment on 2 seperate mixes using DTPA solely in one and the EDDHA/DTPA mix in the other. Also using tap water (hard Lincolnshire water here) to try and replicate the OPs problem. Should also be noted that while tap water will be almost neutral straight out of the tap...

Just to clear up that these packets should mixed all as one lot and not in parts. You will end up getting the wrong amounts of each ingredients because some are heavier than others. There are 2 iron chelates in there. 75% is EDDHA and 25% is DTPA so there should be no problems due to the...

Isn't that what the Apogee does too? I know people use the apogee sensor with a multimeter and then do the multiplication themselves. When there was a side by side test with Apogee and Seneye they were within 10% or so of each other. From what I hear the Apogee has some critics regarding its...

WPG is that old very simple rule much maligned. It isn't accurate at all which is pretty much on point with this thread. You don't need to do any fancy PAR readings or calculations. Quite simply go by the WPG rule and reduce it for LED lighting. Not exact but simple :) PAR meters are cool...

You don't have to pay for it. You have to pay for the members section on Barrreport but if you search hard enough across the web you can find the information you want to find. I think some people are expecting it to be collated in a library like most scientific papers. Tom is all over the net...

I think Tom is more cautious because people simplify things so much and take things as black and white. He could put fully tested information out there and give numbers, ratios and quantities but then someone (or lots of someones) will take those figures as gospel, run with them and then get...

You are over simplifying all the time though. I am not saying that plants need 30ppm. We do not add 30ppm because that is what the plants need. If this were the case non of my planted tanks except the only one which is CO2 enriched would work yet they do. The reason we add 30ppm is to ensure...

That is mad. You are trying to prove that phosphate causes algae by suggesting that we push the light as high as we can and at the same time reduce CO2. That in itself will cause algae because we will be supplying less CO2 than is needed for the speed of growth the light is driving the plants...

If phosphates cause algae then how is it if you put a container of RO water on a windowsill it will grow algae? Where do the phosphates come from that cause the algae? It is more likely due to dust particles decaying / rotting and causing ammonia. That is what most people say causes algae...

Maybe a misundertanding but the 5% was an example made up by me to suggest that plants will not use up all that is added or in the tank. Just because we add 10ppm of something does not mean that if the next test reading is zero that the plants have taken it up. As for the CO2 it is not...

Ardjuna. I get what you are saying but thst is a little simplistic in my eyes. It assumes that what we add stays available and is consumed. From what we add in terms of nutrient and CO2 for all we know the plants might only be able to access 5% of it for any number of reason and the other 95%...

exactly. The reason I say EI can be flexible because even Tom will say that it is a starting point whereas with PPS and PPS Pro Edward used to dictate it was a regime etc and this is what you do and should continue to do. EI by its very name (Estimative) means you are estimating. I have used...

Not sure I agree with that. That statement seems (forgive me if I'm not understanding properly) that plants have individual and independent 'compensation points' for each nutrient/light. I pretty much agree with the statement earlier. All this talk of slowing plants down by limiting nutrient...

I wouldn't call the PPS Pro method easy to be honest. If I remember correctly it start s reasonably simple but then there's testing and altering the recipe over time? I think Peter Kirwan (Zig) has used it.

Yep forgot to mention I always use DI water for solutions. Just means you are starting from a base of zero then adding your own stuff in. Your water report may well show high phosphates in your tap which could also be reacting. On the calcium part my tap water both cold and hot can quite...

2 things :) Firstly - When I mix up a solution I leave it on a warm radiator for a day shaking it every now and again which helps. The other thing is that you are missing out the obvious. If you make the mix with double the water then you just dose twice the amount. or with 4x the water and...

np ;)

Not claimed Tom ;) It's good stuff. I've been using it for years :)

Tropica uses HEEDTA which I would assume lasts longer than gluconate or EDTA. The weekly thing is precisely as above said. Many people would buy the fert that says dose weekly instead of daily. You underestimate how lazy (even unintentionally) many people are. We dose daily quite simply...

0.4ppm is supposed to be the borderline for shrimp problems. Thats in the region of 2x EI if I remember rightly (maybe a lot more than that) So you won't have a problem. The only problem I have is the weather is too cold and therefore my shrimp colony must be 1000+ at the mo. lol I dose 8%...

Just as Ceg says. I was dosing only the EI macro mix monthly or bi monthly on my non CO2. no water changes etc. Depends on your plants and also stocking though. Heavily planted fast growers will eat up the natural NPK whereas just anubias, crypts, ferns etc may need minimal supplements...

This is quite a good mix for testing. bit expensive for larger amounts though. Has DTPA and EDTA mixed in together. http://cgi.ebay.co.uk/Chelated-IRON-8-E ... 27b46b632a On a side note its quite embarrasing the 'pride' felt when seeing the first bubble come from the DIY CO2 setup. lol...

I just read the thread from the beginning and I've wasted a whole page repeating whats already been said. lol. Bad habit I have there. 'MUST READ THREAD FROM START' he says whilst knocking the spheric shaped wooden object on shoulders with knuckles. In short Tom's recipe was 1 tablespoon of...

depends if 'Ferrous Fumarate' is any good for the plants to use. Tom describes Ferrous sulphate in the link someone provided at the top of this page as 'adding rust to the water'!!!. Many sources for iron but not all 'available'. With those iron tablets they do have lots of other things in...

Does anyone have a spare 20g or so of this? Andy

Yup, nice link. The mix I am looking at from barrreport is 1 tablespoon CSM+B and 1 teaspoon of gluconate to 1 litre. Just got to weigh up a comparison between CSM+B content and AE's orginal trace mix that I have now. Also all the barbling I have done above and I notice that our very own...

Any idea where I can buy ferrous gluconate in powder form in the UK? Will Folic acid tablets be any good. They contain some ascorbic acid. AC

So in the space of a couple of hours I have proven myself wrong :) Is goodthoug. I am just as happy to be proven wrong as to be proven right because it means my knowledge and understanding is increased. The overall mesage I am reading from Tom and others in these threads (and more I haven't...

because TPn+ has very low levels. Plus other acids and thingys. JamesC would be best to explain theat conundrum.It may be the quantity that causes the problem. If it were a constant we would be able to dose only one or the other. However in answer to the original question here is TomB's...

Haven't read this before but it intrigues me. Seems like a step backward in thinking. I thought that these days we dismissed the red=iron suggestion. Also With iron we understand that it is very quickly locked up by phosphate when it goes in the water. Hence high iron and phosphate = milky...

On the day the site (and images) were created. Thats not cynical of us. No site will come up on a regular search on the day it is listed. No time for the search engines to index. And what were you searching for to see it come in the first 10000 pages? JT+aquatic+plant+food? Its not us...

And the special offers on that site are: TFF Fertiliser mix TFF Fertiliser mix 500 TFF Fertiliser mix 1000 TFF Fertiliser mix 2000 which are: the ferts made and sold by the 'homepage' in jonnys profile and also is remarkably similar to another fish forum we all know :) abbreviated to...

It's not yours is it? ;) just considering it an extremely fast entry into a search engine seeing as it was written today ;) No time to index etc so it would be on page 999,999 today if it showed up at all!!! AC

No idea if anyone tested for uptake. I would guess that there are tests for toxicity around. Maybe on the barrreport: http://www.barrreport.com/showthread.ph ... r+toxicity http://www.barrreport.com/showthread.ph ... r+toxicity Seems that Tom was suggesting 0.5ppm is quite high. however...

You'll hate me but CO2 again is the answer to most of your questions :) Many plants shoot up because they need more than CO2 than is available at the substrate level. The CO2 concentration will be higher further up the water column by it's very nature of gas rising :) I think Tom would verify...

When I was running CO2 at '15ppm' (of course I was only going by 2 drop checkers in the same tank with 2dKH in them) I found JamesC's PMDD+P worked pretty well if that is any help :) AC

I was just trying to clear the other subjects out really. They aren't anything to do with EI in the main. Like Tom says EI is a method that makes nutrients easy, especially for those who don't want to test, or calculate etc. I see what you say about laziness being forgetting to fertilise etc...

I agree with Saintly, GE and Tom on most points here. When I had CO2 and got the circulation right I could do any amount of pruning I liked with no fear of algae. before I got the circulation right whilst still the same rate of injection I got lots of algae issues especially after a mad...

As with all things there are examples of success with textured backgrounds. Different people have different setups and learn to master their own setup :) I have seen a lot of problems with structured backgrounds though :) I would think it would be one of those things that is not a problem to...

I'll not cover old ground then BUT I will say this r.e. My current scape and previous scape had only 'slow growers' being ferns, anubias and crypts!!! My substrate is Tropica with sand. Even though I had what many call low light (0.9WPG T5HO) over a 125 Ltr and therefore many would suggest...

Paul - it is your decision at the end of the day and we have to respect that. I would just say that I have posted many times that I wish that forums when I began were at the stage many are at these days where lots of people can give the advice that cuts out the spend trying to get to the holy...

I do EI daily 7 days a week. I tend to do my water change either during the final hours of the photoperiod (my photoperiod is 3pm - 12am) after the CO2 has switched off in which case there will be enough left / already consumed during the day. Or I will do the water change in the morning pre...

ADA tanks have lovely carpets of HC and whilst the tank owners believe from the technical specs that their beloved ADA lighting units are highlight this has been proved wrong by tests done by TB at AFA where he tested a load of the ADA competition setups and found the ADA lighting rigs to be...

That is why so many blame a method for failure and never reach the holy grail ;) Believe me I was one and was banned from this forum for 'getting sick' of the CO2 statements. However I can vouch for their validity. Even if the method is PPS Pro and low dosing. you may blame the method but...

ADA can be quite 'cheeky' when designing their items. One of Tom's favourites are their light systems which when tested turn out to be relatively low light. On paper they are highlight which of course means that not only the ADA addicts buy them but also the ones that would be put off by a...

I think it's more a case of the translation here. Ammonia is a nutrient basically. They sell Iron 'bars' to put in the substrate so that one's a gonner too. lol Maybe be better to 'do as they do' rather than 'do as they say' where translations come into it. AC

Removing carbon when dosing meds is an urban myth. Removing FRESH carbon when dosing meds is what should be said. After a certain amount of time which is argued about by many people the carbon is 'exhausted'. Carbon adsorbs not absorbs so things 'stick' to it rather than being soaked up by...

Mine have gone 10 days before when my folks were also on holiday while I was away :) I put an auto (cheap mechanical) feeder on the top set at as low as it would go so that it wouldn't 'dump' and then got in the car for the airport. I don't trust them but it will at least work a couple of days...

I always go away for 2 weeks + in the summer and I turn off the CO2, no dosing and set the lighting at the bare minimum for the duration. I normally come back to an overgrown tank :) Oh and I get my Dad to feed the fish twice each week. ;) AC

I think Zig has had some success with it. Maybe wait for him to see the thread. I myself used it a long time ago before I got on top of CO2 and flow problems and due to this it failed very quickly. I found JamesC's PMDD+P muchmore forgiving and that is also lean dosing but nowhere near as low...

ADA - Iron Bottom aka - rusty nails . :lol: http://www.adana.co.jp/_e_product/101_index.html or cheaper on ebay :lol: http://cgi.ebay.co.uk/ADA-Iron-Bottom-F ... dZViewItem AC

ADA already sell these :lol: I'm not so sure of whether it is an iron defficiency but it shouldn't be if you are already adding trace. AC

I don't get milkiness and dose both daily. I don't do an all in one however I mix the KNO3 and KH2PO4 together (in a different ratio so that I dose the same as if they were seperate) and the trace is in a seperate bottle. By the time you get to the traces the KNO3/KH2PO4 mix is diluted and...

When I had a job ;) I used to dose at 6-30am in the morning every day when my lights come on at 3pm. Never caused a problem. I now dose much closer to the 'on' time but will go back to the 'old way' if and when I go back to work :) AC

I think you'll find that Crypts are actually incredibly heavy users of nutrient!!! Forget the 'heavy root feeder' theory. Dose the water column and it takes the strain off the substrate. The amount of Crypts you have will strip a substrate clean if they can't find their 'food' in the water...

How are you testing? almost 0 from tapwater sems a bit low to me in the UK. You will also have some P from the heavy feeding of discus!!! AC

quote (in square brackets both ends) then the copy/paste part then /quote (in square brackets both ends) AC

Using a 10ml syringe and pulling the plunger all the way and then squirting a little back into the bottle till the plunger is at 9 is pretty easy to dose IMO. similar for any other measurement under 10ml. I use a 3ml syringe for my dechlor (pond dechlor) which works out at 1.3ml per bucket...

Don't worry about the levels unless this changes I would stick to what you have if it is working. Don't worry about EI. EI is mainly a setup for making it easier to succeed. If you are succeeding with using a different method then thats fine. It would be quite hard to implement EI using an...

I tend to weigh mine out still. something to do ;) I make up 500ml of my 40g KNO3/9g KH2PO4 mix. (I dose 9ml daily to get the same as 20ml/12ml 3 x weekly) Then I make up 100ml of trace with 6g trace elements and dose 3ml daily. When I have made the KNO3/KH2PO4 solution I give it a good shake...

The answer to your question is: It doesn't matter how close to EI you are!!! If it ain't broke don't fix it. I would however keep an eye on the CO2 ppm at that temperature. O can get depleted much quicker at higher temps. Nitrate and Phosphate are there in reasonable amounts (assuming the...

http://www.barrreport.com/co2-aquatic-p ... tanks.html http://www.barrreport.com/fish-planted- ... -tank.html

need more details of your tank and regime. Please don't use text speak as it can be annoying for some of our members. No need for testing and its EI which is a regime that means no testing is needed. From the little info that is of use from your first post you have highish light and very low...

Not to put a spanner in the works but are we challenging the 'current belief' that ammonia triggers algae? If so an the point you make is that the main 'knowledgeable' fert suppliers use ammonia can we not already assume that this 'belief' is in someway false?? Going to Diana Walstad's...

The concentrations although looking much higher in copper etc. are still small. AC

What I was implying with the last statement in my last post was that there is huge investment in garden ferts research whether just for composts or for ferts such as ours. Much more than in aquatic ferts. I would guess the research funding is maybe equal to turnover of aquatic ferts!!! I also...

I don't think many suppliers would worry too much about the price of Pot Nitrate. Its phosphate supply in its various forms that sky rocketed last year to the point it was darned hard to get for the fert companies without pre-ordering heavy amounts (talking ordering whole year's supplies in...

I used to add the magnesium to my macro mix AC

I use tap water ;) DI water costs money :lol: AC

Although on lean dosing I add magnesium anyway. Can't hurt so why not. For the price of it and how long it will last it doesn't add much extra cost anyway. Same with the argument for and against adding Potassium sulphate. You probably get enough in your KNO3 and KH2PO4 but it doesn't hurt...

Depends which teaspoon you have!!!! I have many teaspoons and they all vary in size and depth to the point that I use the same type everytime for making coffee! A teaspoon in measuring terms is a proper measuring teaspoon whereas a teaspoon in kitchen terms can be vastly different from 4-6g...

To make a 'roughly' 4dKH solution you need the following: 5Ltrs DI water 1 Ltr DI water 6g Bicarb First add the 6g Bicarb to the 5Ltr of DI which should give you in the region of 40dKH water. Shake it well and then using a syringe take 10ml of this solution and put it in a clean, dry...

If you follow EI then you 'should' be dosing enough. As Ceg points out above I have no experience really with larger tanks so I think someone else would be better pointing you there. I personally am too lazy for 50% water changes even on my 125Ltr. I think with a tank the size of yours I...

Henrik. Put your location in your profile and then people in similar areas will know where you are and will have a rough idea of any problems you may face water wise from their own experiences. I use the AE trace and just make up small 100ml mixes (just in case) If you are dosing dry then it...

The answer is I'm not sure that 10-20ppm is the most one would ever need. I am taking that from what I have read from others on here and other forums that we all use. I have no idea. I add 2ppm nitrate a day and it works for me. How much is in the tap water? I don't know. How much of that...

Tom you misundestand us I think :wink: We are not saying excess nutrients are bad nor cause algae. more a case of why dose 3 x what is already excess if it can get close to the levels that 'could' be harmful wether that had level was know or not. If 10-20ppm per week is EI then why dose...

Why would anyone want that much light? surely a couple of T5HO with their better efficiency would do the trick ;) And why would anyone want plants more finicky than crypts and ferns? Everything else is rubbish ;) :lol: What do you mean by finicky anyway? I think anything would grow in mine...

Why would anyone want to double or triple Nitrate levels anyway? If 20ppm added weekly is the most plants are going to uptake and then another 20ppm is added (through the 40ppm within the 50% change) then what is the point of doubling tripling unless you were short dosing in the first place...

A fair few of us have been using a PMDD+PO4 daily recipe for quite a while albeit a leaner version with lower water changes. AC

Those quantities are correct as long as you stick to the mixes on JamesCs site. If you want to make bigger solutions then multiply the chemical by the same multiple as you do with the water. The acid is to stop fungus etc in the trace mix but I never bother with it. The speed your 250ml mix...

If going by the basic EI dosing guide you don't need to play with the quantities within the solutions. They are basically calculated on ideal amounts that the chemical will dissolve at and to make things easier. All you need to then do is work out the quantity of ml from the solution for your...

As far as I know both TPNs do have K in them. Its N and P that are missing from the 'non plus' version AC

As per previous posters. changing dosing won't prevent GSA unless you already had something wrong with your dosing. Anubias are always susceptible to algae especially GSA. In my tank the leaves that are at the top are totally GSA free whereas the ones that are under the others tend to get GSA...

But we are saying here that good flow and a little turbulence brings in O and this helps keep the algae at bay. We already have good growing plants and most of us have as little algae as Diana, some less so I don't see what you are saying here. Both Dianas tanks and ours have plants growing...

Dusko - I think this theory has something to it and last year I commented on how the clarity of my water seemed to have improved considerably (it wasn't that bad before) when I left the lily pipe a third above the water level producing much more turbulence and producing O bubbles moving around...

Just me remembering searching Wiki before (I remain oblivious to most non-basic science) Could it be due to Urea being created from Ammonia and CO2 that in some way it counteracts itself in that it can supply C and N at the same time? Probs wrong but would be a natural assumption for a...

If you are 'assuming' then it is not 4dKH. If you had 4dKH you would've bought it as a seperate item or made it yourself. As with all manufacturers of equipment, their way is not always the best and I am guessing your instructions are something like 'add tank water to the DC and then a few...

This is what I have to do quite often due to my plantmass. As it affects the flow I have to search the tank for a 'new' best position for the powerhead, diffuser or both. AC

As long as your CO2 is up to scratch and you up the ferts then the probable outcome will be that a couple of weeks down the line you see a vast improvement. I shouldn't worry too much about being over cautious with these recipes. Its better to double dose and bring it down than it is to...

Ceg. I have a light grass green DC and I can see the swathes of CO2 bubbles shooting out of the powerhead along the back of the tank. I can even see them coming back around the front of the tank to complete the cycle at the same end they started. On top of this I dose the recommended dosage...

My Co2 must keep running too low (or not dosing enough nutrient) Every leaf I damage gets staghorn or BBA within days. I shall have to keep an eye on it. AC

Are we talking the All in one or the DIY TPN+? If the former then for 325ltr it should be (25ml / 200ltr) x 325ltr = 40ml (assuming same lights etc.) If the latter then it should be (1.5ml x 325ltr) / 50 = 10ml (again assuming same lights etc.) All these type of regimes where the dosing is...

Ceg, although I agree with what you have written above you concentrate on malnutrition. Should it not be added that the slightest damaged leaf will have the same effect ammonia--->algae wise? This is easily shown that when doing a water change with a syphon (and I am not the most careful) that...

By using digital scales (£7-10 off ebay) or real measuring spoons which will be in a set and include all the increments. or by eye. It isnt exact science, measure 1 teaspoon and then split that into 16. No need for extreme accuracy here. AC

It may seem a small amount but with our size tank and WPG it will be a slight excess. You wont go defficient but equally you wont be dosing as high as EI. If working it out properly we would be dosing a bit less than 2ml in comparison to JamesCs high light! The target ppm of phosphate is alot...

After buying the trace elements from AE I wont buy from anyone else again. The powder is so fine and has absolutely no grain size to it. It is basically the texture of dust and therefore nothing is left at the bottom. Top marks. I can get them cheaper but for the small difference in price...

What I am saying is that with the powder that you already have, mix it and dose it as suggested by whoever you bought it from and hope that it supplies enough of each nutrient. Then mix up 500ml of water with the quantity of KH2PO4 suggested in JamesCs recipe and dose 4ml total per day. Next...
