Thanks, yes possibly, I did think it should gradually fade to darkness rather than darken in stages.

Here is a video showing the light behaviour 1 minute before "off" time, is this normal? Aquasky 2.0

I swapped the light for another which was easy thanks to my local Maidenheadc aquatics. The replacement light behaved in the same way ☹️. Fluval are still investigating as it should not behave like this. Just wondering if anyone that has an aquasky 2 could see what their light does just before...

We currently have the pre-filter foam in the prefilter tray at the top, then from bottom basket upwards, Eheim Mech ceramic tubes (took the Eheim mech pro out as they kept floating up when cleaning the filter and removing baskets), next basket is filled with Eheim Biomech, next basket is Eheim...

Its an Eheim 2074 350T thermo filter

try without the fine "polishing" filter floss pad? I'm using ceramic tubes at the moment and he seems to say they are not very good at mechanical filtration.

I recently watched several videos by Pondguru, he says its best to place mechanical filtration in lowest basket as that is the first basket the water passes through after the pre-filter foam. As the mechanical filtration is teh first backet the water encounters, it leaves the biological...

When I called Fluval tech support he seemed to think it maybe faulty, he said it should not switch between normal light and green light momentarily before the off time. I missed a call back from him, I'll call back on Monday to see what he suggests.

Thanks, is not very gradual for me, it's seems to have a stepped gradient in use. For example 10 minutes before the end of sunset it still seems pretty bright where I would expect it be almost off.

I recently replaced the LED light that came with the Fluval Roma with an aquasky 2. Its running in auto mode with an 1.5 hour sunrise and sunset. Should it dim from slowly and consistently dim during the sunset phase ? I just watched it about 3 minutes before sunset end and it dimmed, then...

How often do you clean the filter sponge?

Good comments guys, yes I was asking about the effect of higher o2 on BBA, and although I know it will not kill it, it should help stop it spreading along with an enhanced cleaning schedule. Removal will only be done as said by chemical intervention of removal of affected leaves. So I think...

Brilliant thanks for the information, maybe I'll go for a skimmer as it would be good to get rid of the surface film we have. Not sure about which one yet, I like ehiem products as they seem well built, so may end up with that one. We don't have any RCS, just Amano shrimp, lemon tetras and...

So would go for the aps one? How do you fix the Eheim one to stop fish being sucked in?

Should I get a surface skimmer then? They seem cheepish at £20 for an Eheim 350. How long is yours on for, overnight only?

We do water changes every week with monthly or less filter cleans and we change about 42 litres of our 100 litre tank each week. I have an old air stone so I'll put that in on a timer to run overnight for a few weeks and see if it helps stop the spread of this algae and improves the overall...

I've been reading about BBA and it appears extra Oxygen is helpful to ensure organics in the tank are broken down better. I know BBA is potentially caused by a build up of organics so we have upped the water change to 4 buckets a week rather than 3 and also are feeding the fish a bit less. Has...

Thanks, I've read the BBA threads on here before and it appears to be a maintenance issue mostly. We have Armano shrimps in the tank so I think I need to be careful with easycarbo

Thanks, its seems to be on the edge of most leaves in the tank, even the leaves in strong flow.

Can anyone advise on this for me?

Having a few issues with what I think it's BBA, can someone confirm from the photo attached please? If it is I've read that easy carbo is a good way to kill it.

Yes agree, well that's what I later found out. However a lot of articles I was reading mentioned rations of 10:1 which is why I posted the questions. I still not having great success with some plants in the tank which just melted away over a few weeks so I guess something is still not quite...

A quick update, still not getting any growth from the Hygrophila mini, its just about hanging on with a few leaves left :( Maybe these plants dont like water at 11 dGH?

Thanks just got 2.5L of de-ionised water from Sainsbury for £1, remixed and within hour all mixed in with no settlement. Thanks Darrel.

Per Perfect thanks Darrel, we have some precipitation with our solution. If boiling then what would I strain it with (how fine should the strainer be)? thanks again

A quick follow on question regarding this. Should I be using just normal tap water to make up my dosing mix? Been reading about people use RO/distiller water, or boiling the water etc.

Ta, so we should be putting in more than 0.7ppm a week? Any suggestions or should I just up it to 1ppm a week and see? Can you put in too much fe?

We are dosing 10ppm of MgSO4 a week

We are now using TNC Fe which uses DTPA, should this be sufficient in our water? Thing is I am still seeing transparent new leaves on some plants, which I believe is an Iron issue, or do I have this all wrong?

I meant tanks, sorry did not read whole thread :banghead: These newly packaged plants look interesting.

well Well the issue is with new leaves, also the old ones break down and die, the leaves on the effected plants just look more yellow than green

Our pH out of the tap is about 7.2 to 7.4, after 24 hours its 8.2 to 8.4. Measured during lighting period with injected co2 its 6.9 to 7.0

I read that as we have alkaline water (pH > 7) the chelating agent used in Seachem iron (EDTA) breaks down in water with pH over 7

We've had Tropica in our P@H for years now, I remember going in there 5 years or so ago to find amazing large tropica plants at amazing low prices. Its just a bit hit and miss what plants they have on a week by week basis.

We dose iron alongside Tropica Premium on Monday and Wednesday, and dose the rest on Sunday, Tuesday and Thursday. The water seems to tint yellow by the end of the week, not sure if this is caused by the iron not breaking down properly? Are the levels I'm dosing correct. I am seeing GSA on...

Have had the new setup running now for 2 months, and I am still seeing what I think maybe iron deficiency with new leaves looking transparent with yellowish tips. I'm running a 100 litre tank with an eheim 350T filter (so about 10x flow). Injected co2 on before lights and off before lights...

Looking at this site I think the issue may still be Iron deficiency "Leaves yellowing from the tip then become transparent - Iron deficiency" https://www.ratemyfishtank.com/blog/diagnosing-problems-with-aquarium-plants

The plants still seem to be struggling, the Hygrophila mini is melting way in the foreground and the repens now has some small leaves on the stalks, but its not growing very fast (looked the same for a a few weeks now). Could I be dosing too much?

Seems that Bandit cories are very illusive, as I called my local fish shops again yesterday and still no Corrydoras metae, so none since I started this tank 2 months ago :(. WHERE ARE YOU CORIES :arghh: Seems these things are seasonal from what I have heard, so does that mean they are not...

1 week from Monday to Monday, so thought dose as normal on Sunday, then make up some bottles for neighbour to pour in for each day from Monday to Thursday. Thinking should we do water change when we get back or keep dosing for the second week as per routing and do the water change the following...

You will need two timers, one for lights and one for gas

Start with gas on 1 hour before lights and gas off 1 hour before lights off. Get a drop checker as this will give you an indication of the Co2 ppm. your are aiming for a green/lime green colour when lights on and it to stay this colour until lights off. Trying to achieving this colour will...

As far as filtration goes the rule of thumb seems to be 10 x your water volume, so for you about 1000 litres per hour. I have a 125 Litre tank and use a Eheim Pro 3 thermo filter which outputs just over 1000 lph. When you say Eheim 650 I assume you are talking about the Eheim 650 powerhead?

Cheers, hopefully it will look better soon :). What do your do when your go away as far as dosing goes as we are going away soon? Thinking of asking neighbour to dose as they will be feeding the fish anyway.

A quick update, 1.5 weeks into EI I can see some changes now in the Hygrophila, the new leaves look much better, still some brittle, yellow, glass like leaves on the Hygrophila mini at the front of the tank though, so hopefully time will improve this plant. The Staurengen Repens stalks now...

Should i consider buying more if its gone lumpy?

Interesting, our containers are not air tight and the kno3 and kh2po4 has lumps in. The mgso4 is okay. If it has lumps is it still okay as not sure that question was answered in the the thread you posted.

Do dry ferts have a shelf life? We are using some we bought over 5 years ago and are still seeing some plant deficiencies even dosing ei levels, Jenner wondering if it's not as potent over time. Ta

Okay I am looking at levels of 20ppm or so, so it sounds pretty safe at that level then.

Just wondering if you can have too much sulphate in an aquarium and is it harmful to fish? I dose mgso4 and am thinking of dosing k2so4 as well, and so will be adding lots of sulphate (so4) to the tank water. Sent from my SM-G935F using Tapatalk

Lol let's hope mine gets back on track soon. Sent from my SM-G935F using Tapatalk

Would it just be easier to throw your existing mix away and start again. You will use 0.6tsp of KH2PO4 in the new solution and 6tsp of KN03, rather than add another 11 or so tsp to try and correct your existing mix.

I was going trough the same as you, hence my thread on ratio as my Po4 was way too high. So based on what you want which is 1ppm of po4 and 10ppm of no3 per dose you will need 12 tsp of kn03 and 1.25tsp of kh2p04 which will give you your 10:1 ratio per 10ml dose, so if you want to do a 20ml...

What are you dosing? KH2PO4 and KN03? if so are you trying to get to the magic 10 : 1 ratio for ppm as I maybe wrong but thought this was for K and PO4 rather than NO3 and PO4.

HI mate, What quantities are in the bottle now and what dosing are you aiming for?

Yes thanks, the 10:1 ratio works with PPM as far as I can tell. By looking at the EI guide that Clive wrote, 30ppm of NO3 and 3ppm of PO4, so 10 : 1. Yes I understand its not an exact science, but just curious :)

Is the 10:1 ratio the ratio of NO3 compared to PO4 in terms of PPM, rather than the quantity of the salt you add to your solution bottle as the percentage of NO3 in KNO3 is not the same as the percentage of PO4 in KH2PO4 ? So my question regarding K2S04 is because I think using just KNO3 and...

Adding up the Mg, it looks like i need to add 27 tsp to 500ml of water to get total 10ppm a week dosing 10ml 3 times a week. Is this right as it seems a lot of tsp's to me. Also how do you get the 10:1 balance using KN03 and KH2PO4 ? Do I need to use K2SO4?

So the 10:1 ratio for no3 and po4 is what to aim for?

Thanks Darrell, should I follow the article by Clive as that seems to have 10:1 ratio seems more in line with what I have read? https://www.ukaps.org/index.php?page=dosing-with-dry-salts

I've read that I should be aiming for 10:1 ratio of NO3 : PO4, however is this really NO3 : PO4 or a ratio of N : P and is this old advice? Also if PO4 is higher than that does that cause an imbalance and thus can cause algae issue? Then again I've read that you can add more PO4 without issues...

Thing is the s repens are right in the flow Sent from my SM-G935F using Tapatalk

Just took some photos of the drop checkers, both with the same water and reagent, what do you think, does the JBL look bluer or is it a optical illusion?

RB only states N, to get NO3 from that multiply N by 4.4. When I put in "Results for my dose" and entered 16.8ml (which is my total dose for the week) I get 2.251ppm, so multiply this by 4.4 which equals 9.9ppm of NO3 for the week from Tropica Specialised. Also I think 10:1 ratio is between...

Okay so after a bit of research, I think for EI I should be aiming for the following NO3 range 5-30ppm PO4 range 1.0-3.0 ppm K+ range 10-30ppm Fe 0.2-0.5ppm or higher I think we are putting in the following Dry mix a week NO3 - 15ppm PO4 - 4.68ppm K - 11.01ppm Mg - 1.8ppm Tropica...

Going to work out my dosing and see how much I'm putting in. I'll do some research on ei as well to see what quantities of each I should be putting in.

Yes just thought about that and was just going to post on that.

Our yes Rotala Butterfly, I have looked on there as well but as I don't want to follow EI so I've been doing about half of what it tells me for EI, so for 100L (125L - substrate etc) it says 28.6ml, so divide 2 = 14.3ml which is a bit less than we are dosing of N + P. Interesting though is we...

I noticed some BBA on a crypt leaf towards the middle of the tank, which I think is sign of low / fluctuating Co2, so I'll go back to make sure that is correct as well. I've added KN03 and MgS04 to our dry fert mix as well.

Where did you find this advice ? When I look for dosing guidelines all I find is what it basically says on the bottle, so for a 100L tank, it would be 10 pumps a week. We are dosing 14 pumps of Specialised and 7 pumps of Premium a week. Ta.

I'm still wondering if the cause is a lack of iron. I've been doing some research and glass like new leaves with green/yellow tips seems to be a sign of iron deficiency. My Hygrophila has glass like new leaves with green tips. Also the Staurengen Repens is going from bad to worse, attached...

Hi, Added the information to my tank journal, any advice much appreciated, https://www.ukaps.org/forum/threads/a-place-for-corydoras.49696/page-2 Cheers

We have only used and 30ml of it, so I think I'll just add to that and see how I get on. To start with this week I'll add 1/2 a TSP now and upon water change on Sunday start using the bottle. Sent from my SM-G935F using Tapatalk

So if I put in 6 TSP into 500ml, each dose of 10ml will give me 4.41ppm. So over the week id get 13.23ppm as I'm dosing 3x a week, is that a good starting place?

Brilliant analysis and very informative reply, thanks very much. I do have kno3, so 1/2 TSP a week would be what ppm a week as I'm thinking I could add it to the kh2po4 solution which I dose 30ml a week?

None on top of what is in the Tropica solution. Although when last tested it was between 5ppm and 10ppm.

some more specifics about the dry ferts... Used this http://www.theplantedtank.co.uk/calculator.htm to get 1.84ppm Phosphate and 0.76ppm of potassium. To get that I put 2 teaspoons of KH2PO4 in 500ml water and am dosing 10ml 3 x a week.

well... 2.4 ml (2 squirts) of Tropia Specialised daily, and just started 1.2ml (1 squirt) of tropica premium daily. Co2 is now at ph6.8 (water is 8.2 after 24h) when lights on (lime green in drop checker) We dose the dry 3 times a week.

Hi, Had the tank going now for nearly a month and recently noticed the following with the Hygrophila. As you can see from the picture, new leaves appear transparent and some of the older leaves seem crinkled in appearance. Also our Staurengen Repens is losing it lower leaves, again these seem...

Higher agitation seems to have fixed surface scum and the co2 now gets to correct level by lights on. Now just to keep the plants healthy

A quick update on the goings on in the coryless tank. Having a few problems with the Staurogyne repens, they lost all their lower leaves (just floated) off. The Alternanthera Cardinalis is still getting holes in its leaves. Now dosing 2.4ml Tropica specialiseddaily + 1.8 ppm of po4 and 0.76 of...

I had some surface scum with lower surface agitation, bps at 1.3 and at this rate it took about 4 hours to go from 7.4 to 6.8 before lights on. So this weekend I upped the co2 to 2bps and increased surface agitation, pH at 7.6 before lights on and 6.9 when lights on. Decreased gap between co2...

Thanks for the reply, the Staurogyne is losing its bottom leaves, and some leaves now appear translucent. I'll update my journal shortly with a few photos. :)

Thanks for the link, I think I may have read that a few years back, I joined here in 2008 and had varying success with a 240l, 70l and 125l. After a few years off I'm just trying to get my head back around the process and anything that may have changed (LED lights for example) since I was last...

The other day I left our tap water for 24 hours and then tested the ph, the reading from the tap was 7.4 and after 24 hours it was 8.2, however the KH is still 7 so I'm still aiming for 6.8 - Is that right? Yesterday I upped the co2 to 2 bps and increased surface agitation, the ph drop was...

Thanks, it's on at 13:30 with lights on at 16:00. Should the pH level be at 6.9 for 4pm?

So is this profile good or bad? If it's bad any suggestions on how to improve it? Thanks

I always ran my Roma at 8 hours as those T8 bulbs are not very powerful. I think up the lightening and keep an eye out for any algae, as determining what type appears is a good indicator of what is deficient in the tank.

So I may experiment with a higher bps rate to see how quickly the pH drops as without a pH controller I'll need to manually monitor during the light period. Sent from my SM-G935F using Tapatalk

The lighting in that Roma tank is a very low level as I had one myself a few years ago so I would now worry about over doing the lighting. How much of the "easy-life profito plant fertilizer" do you dose?

Ringing around local fish shops, finding it hard to find some Bandit Corys :( Damn as this scape is for Cory's.. oh well patience.

Yes thanks, during the week I'm leaving it unchanged, tested yesterday evening and PH down to 6.85, which according to the link I found on here to RotalaButterlfy is spot on 30ppm. Now I guess i need to get it to 6.85 for lights on and keep it there for the lighting period. I may experiment at...

Planted Hygrophila Compacta and Staurogyne repens at the weekend.

Anyone?? Sent from my SM-G935F using Tapatalk

Forgot to mention gas on at 13:30 and lights on at 16:00 (the 14:00 on the chart should be 13:30)

Hi, I'm trying to get the co2 in my tank stable during lighting period, I've borrowed a ph pen and have charted morning, co2 on, lights on, co2 off lights off on a chart. Looking at the chart my co2 builds over the lighting period before returning to normal ph for my water over night. My...

How dirty is your glass? Sent from my SM-G935F using Tapatalk

Alternanthera cardinalis cut back yesterday and tops replanted, leaves with holes in removed. Reading a bit more on this plant it seems fairly common for it to get holes in its leaves. PH read 7.4 this morning, hoping to get 6.8 (which I believe is the sweet spot) when the lights come on and...

Well funny you should day that as 2 x pots of Hygrophila compact and Staurogyne repens arrived yesterday. Pots placed in tank for now ready for Saturday. Thinking these can go around the back with maybe a clump on the left? Also thinking of removing the brown cryptocoryne, any suggestions for...

So in a effort to get the co2 under control I borrowed a digital ph meter from a friend. First days use its been really helpful. Before co2 started read 7.04, 2.5 hours after co2 started read 7.2, so slightly adjusted, 3.5 hours later read 6.97 when co2 stopped. Tomorrow want to try and see...
