    Best way to raise GH/KH in a heavily planted tank?

    I'm in complete agreement with Darrel. When I see post like these I cringe because newcomers will inevitably read this stuff and will start worrying about things that absolutely don't matter at all, and that's when they get into real trouble because their attention and energy is spent on useless...

    osmocote, how much ?

    Hi, The concentration can be anything you want, low, high, Astronomical - whatever you choose. Were you aware that ADA Aquasoil has approximately 100X EI concentration level? It just doesn't matter. This is not something to worry about. The idea of having a rich sediment is that you can be...

    osmocote, how much ?

    Wow, I speak really excellent Vietnamese! Anyway DuyHung, the idea is that when you push the ice cubes deep into the substrate the ice melts and the nutrients are released into the sediment. If the nutrient content of the sediment is high then yes, some nutrients wil find its way into the water...

    Lean dosing pros and cons

    No, sorry, high pH water has nothing to do with the free CO2 in water. This false doctrine persists despite all the obvious evidence and information to the contrary. Gases typically follow Henrys Law, which states that at a given temperature the solubility of a gas in a solvent is a function of...

    Dry ferts outside UK

    Hi, It's really not necessary to find any special supplier. Any garden center usually will sell KH2PO4 and KNO3, as well as micronutrient mix. Farmers have been using these generic products for a very long time and we have been using them for decades. If you have access to Amazon or ebay...

    Tropica specialized on RO water.

    As mentioned by Happi, dosing EI inherently means that there is no need for testing. Additionally, trying to micromanage ratios of nutrients is probably the cause of unhappiness. You should simply dose the suggested amounts and forget about ratios. Ratios really does not help to grow better...

    phosphate with EI - higher than 3 ppm?

    Hi John, No worries mate. I understand that we all are trying to get a grip on cause and effect. OK, I can see why some may suspect Fe (either in excess or deficiency) since there is a possible issue of Iron Phosphate precipitation. I'm paraphrasing from Barr's conclusion here: If...

    phosphate with EI - higher than 3 ppm?

    GSA is caused by any combination of poor PO4 and poor CO2. If you are adding the EI target amounts of KH2PO4 then it is unlikely that low PO4 is a factor. One then has to evaluate CO2/flow/distribution. EasyCarbo=CO2, therefore poor CO2 has to be under immediate suspicion. If you are only...

    EI nutrient targets vs. accumulated nutrient values

    Hello, As mentioned by other posters above, there really are no "correct" EI values. This way of thinking, forced by the results of spreadsheets, is one of the things I dislike the most about the calculators. I suggest that you study the background information provided in the EI dosing...

    Magnesium - dosing once or several times per week

    Yeah, both those numbers are insanely high, but it doesn't matter though, as none of these numbers will hurt. What's important is to understand how plants use nutrients instead of blindly following some number on a spreadsheet. You can grow excellent plants using numbers 1/100X of that. So for...

    Lean dosing pros and cons

    Well this sounds like a lot of twisting to me. Are you claiming that Amazonia does not leach nutrients into the water? Are you also now hiding behind twisted words? No one claims that NH3/NH4 doesn't fertilize. When we say that nutrients do not cause algae we are specifically referencing NO3...
  13. ceg4048

    Magnesium - dosing once or several times per week

    Hello, EI really does not specify Mg at all and there are no optimum amounts simply because the levels vary with different municipal water supplies. The 10ppm is very high and there is no way plants require 10ppm of Mg. Is it possible you have misinterpreted the value of 10ppm of MgSO4...

    Lean dosing pros and cons

    This argument is not reasonable and giving an answer "yes" or "no" would also be unreasonable. Whenever someone has a problem in a tank it is first necessary to determine what it is that they are doing or not doing. The answer is not a choice of binary options. An analysis must be performed on...

    New to EI

    Hello, It's a good idea to stop worrying about nitrates. Nitrogen is the second most important element (second only to CO2) and nitrate is not toxic at these concentration levels. I do not think it is a good policy to omit nitrate dosing at the beginning. The best practice is to add...

    Root tabs and/or liquid ferts

    As mentioned by the other posters, there is no requirement for root tabs if you intend to dose the water column. Since plants uptake nutrients from either location you can either use an nutritious substrate, such as ADA Aquasoil or insert nutrients into the substrate such as Osmocote/clone or...

    Confirmation on start-up dosing with EI

    Hello, There is no need to make any adjustments. It's not clear why folks insist on making simple things more complicated. Just dose the suggested amounts and carry on. Whenever you do a water change dose the same amount that you would do when performing your normal water change. If...

    Alternative to CSM+B

    Hi X3NiTH, I'd have to suspect some strange combination of events as I've never experienced or anything like the symptoms described, regardless of my use of either tap or RO. My municipal tap water supplier when I was living in UK was Thames Water - notorious for their poor...

    Alternative to CSM+B

    Hi Michael, Yes it's easy to pick the one that has more of everything unless that one is more expensive. Of all the powders, trace mix is usually the most expensive by far, perhaps not where you live, but around the world it can be expensive. What if your tank is 200 gallons...

    Just started with EI dosing

    Well, lets be reasonable; If you add PO4 to the tank how could there not be more PO4? There is no reason to measure it. This is one of the main principles of EI. "NO MORE NEED FOR TESTING". Many years ago, before the advent of EI, when everyone thought that nutrients caused algae, hobbyist spent...

    Just started with EI dosing

    Hello, As pointed out by Wookii, algae really do not care how much nutrients are in the water. If that were the case then every EI dosed tank would suffer algal blooms, so clearly this concept of nutrients causing algae is false. Exactly, so why even bother to pay attention to sucky...

    Alternative to CSM+B

    Hello, Actually it does not really matter which of those options you use. There is no rule stating that ONLY CSM+B or that ONLY products having the same relative content of micronutrients as CSM+B should be used. When EI was being developed CSM+B was the cheapest and most available...

    osmocote, how much ?

    If you intend to dose the water column, especially using the EI method then I would advise against using osmocote, which is extremely high in toxic ammonia. You never really need to spend more money on root tabs as all you need to do is to prepare small ice cubes using water that you have added...

    Worsening algae after starting EI dosing

    Assuming predation is not the cause, holes in plants = poor CO2. The holes might have been there and perhaps you did not notice them, or, whatever previous deficiency you have fixed now exposes the shortfall in CO2. As mentioned, remove affected leaves and you may want to consider adding Excel...

    Worsening algae after starting EI dosing

    Hi Michael, Although this interaction occurs in non-CO2, remember that the metabolism of the plants is about an order of magnitude lower than in CO2 tanks, so we are much more likely to experience this issue in CO2 tanks. Since non-CO2 tanks are CO2 limited we are very likely to...

    Worsening algae after starting EI dosing

    Well, it's theoretically correct, but there are better ways to accomplish this. I'm not sure why, but I had assumed that you were using an inline CO2 diffuser as I had trouble finding it in the photo. I suggest, if possible to port the gas into the filter by placing the diffuser in such a way as...

    Worsening algae after starting EI dosing

    What I'm saying is that I do not care what chelator is in my nutrient products. Hobbyists do not need to fret as much as they do about which chelator to use. As soon as you put the nutrient products in the water the plants start to absorb them. There are both passive and active methods used by...

    Worsening algae after starting EI dosing

    Hi, OK, that configuration is even less effective than I thought. If I read that diagram correctly you have the spraybar holes pointing down? That only then sends the flow to the back part of the sediment. Then there is the corner unit which is sending it's flow to the longest possible...

    Worsening algae after starting EI dosing

    Hello, A rule of thumb is that if you are dosing EI level of nutrients and the tank experiences nutrient related algae then one must immediately suspect that flow/distribution is faulty. It was difficult to see exactly how your distribution is configured, but it appears you have a...

    Dry dosing NPK

    I agree with X3NiTH. There is absolutely no mileage in worrying about using potassium salts for your nutrients. Any nutrients you dump into the tank when dosing EI will automatically raise the TDS, significantly. TDS as a number in isolation is not necessarily bad. What matters is the components...

    My head is bursting

    Hello, These are all signs of poor CO2 and has nothing to do with EI. My suggestion is to forget about getting perfect nutrients and concentrate of fixing your CO2/flow/distribution. As long as you are adding nutrition then there really is nothing to worry about unless the plants show...
  40. ceg4048

    Typical indication of poor CO2. Holes in plants, if not caused by predation, is only ever caused by poor CO2. Terrible idea as Nitrogen is the second most important nutrient, second only to Carbon. Cheers,

    Adding More Copper to our Trace Mix

    You do not need any more copper. As I mentioned previously, plants only require microscopic amounts of these metals. That's why they are called micro-nutrients. Metallic ions such as Copper, Iron, Magnesium, Zinc and others are toxic as hell. Plants have to devise strategies to chelate them...

    If I were to add a chunk of iron to the tank...

    This is not true. It would only be true if the nail were made of stainless steel.

This is an aerobic process and the plants...

    Dosing Calcium and Magnesium in CaCO3 Equivalents

    Totally agree with Oldguy. Worrying about Ca:Mg ratios is another waste of energy. Worry about keeping your tank clean with massive and frequent water changes and worry about CO2/flow/distribution, which are 1000 times more important than ratios. Cheers,

    As mentioned by Zeus, GSA is typical issue with slow growing plants and is associated with a combination of low CO2 and low PO4.

    OK, fair enough, and as evidenced by the tap water content, sulfur toxicity is also unheard of. No, this is down to the low CO2 levels typical in a non injected tank.

    Hi Kingy, OK, thanks for the photos. There appears to be a couple types of diatomic algae typical of newly setup tanks. Theoretically, the algae should go away by itself after 2-3 weeks, however, the situation is often exacerbated when we make mistakes, such as having too much...

    Hi Mohamed, Nitrogen uptake and assimilation are tricky. On one hand, the N that is bound in NH3/NH4 is very easy for plants to use and is more abundant per unit weight. For example, NH4 by weight is mostly N since the Hydrogen (H) is the lightest element. In NH4 78% of that...

    Hello, I agree with Andy. Low tech tanks, i.e., no gas and no Excel, really do not need EI levels of nutrition. So you only need to dose a fractional amount once a week or so. EI assumes the tanks has high lighting and fuel injection. Barr's non-Co2 method is as follows: Assuming 80-90%...

    Hi, I agree with the others. In terrestrial mode there is no advantage in misting with fertilizer and indeed the risk of burning is high depending on the composition of the fertilizer. Keep it simple. Flooding the tank is when your real problems will start. The tank looks good to me as is...

    Is Tropica Premium Nutrition chelated or salts?

    Yes this is really odd because a member based in Holland had asked for some help regarding this. Perhaps the rules are that you must furnish the data to the governing body but that it was not necessary to list them on the label. Cheers,

    Is Tropica Premium Nutrition chelated or salts?

    No, its based on the past history of vendors who refrain from listing their contents. This is why I used the modifier "typically". It's also been our experience that when vendors refrain from listing their active ingredients, it's "typically" because the ingredients are easily obtainable and...

    Daily vs Weekly dosing & water changes

    Hi, It's very difficult to provide a concrete answer because first of all, no one truly knows the composition of your water. It would require very expensive equipment to determine. Unless you are replacing the removed water with RO it could easily be that your water addition is adding...

    Is this ok for an all in one mix

    Hi, I agree with Darrel. If you know what you are doing then nutrient mixes using NH4/NH3 are very effective. If you are asking the question however, then you most likely are not familiar enough and should avoid NH4/NH3 due to toxicity. As mentioned, use any Potassium Nitrate containing...

    Ferts & TDS

    Hi AWB, As I mentioned, the graph cannot isolate how much decline is due to nutrient uptake and how much rise is due to substances introduced into the water column. Nutrients are also pulled from the substrate as well as the water column and the substrate itself binds some...

    Ferts & TDS

    This is really an unnecessary complication. Just dose regularly and carry on. You'll never be able to tell when plants need a dosing just from the TDS. If you are waiting for a color change then by the time the change has occurred then it is already too late and the plant is suffering a nutrient...

    Ferts dosing

    Hi, As usual, this is a CO2 issue and has nothing to do with nutrients. As mentioned by Zeus and Ian, lights, flow and CO2 need to be addressed. Cheers,

    Potassium deficiency?

    Hi, I'll have to disagree with Darryl here. Potassium deficiencies are rare and these symptoms would be the right symptoms if this was terrestrial growth. If these symptoms appeared during submerged growth then it is more likely to be a CO2 issue. Cheers,
