@palcente #1 calcium nitrate (highly react with CO3) Urea Monopotassium phosphate (can cause issues) Magnesium sulphate (source of So4, also react with CO3) potassium carbonate (source of CO3) #2 calcium nitrate (react with SO4) urea Monopotassium phosphate (can cause issues) potassium...

If whatever Kyle said is true, then we still don't need to use seachem equilibrium and sodium bicarbonate to boost GH and KH. You still have a better option which is Cacl, CaSO4 and MgSO4 for GH and KHCO3 for KH, but again this will also raise the K to significant number. Sodium isn't essential...

@Jamsim It's best to use combination of CaSO4, CaCl and MgSO4. while CaCl is highly soluble compared to CaSO4, it also adds excess amount of Cl. If I were to pick Cl vs SO4, I would rather have SO4 in little excess. But everyone have their opinions. Am not a EI user but your Potassium is...

@Gorillastomp you do not have to dose any N and P in your discus tank if you had been doing that. You only really need to dose small amount of Fe/Traces/K daily if possible or every other day. This will resolve some of the stunting issues by itself.

Valid points, but once either one is added to the aquarium, both are highly prone to prectipations and oxidization, Even though Fe gluconate might look more superior due to its ability to form chelation/complexes. This bond is still extremely weak and can be easily overcome by oxygen...

Precipitation of Fe and PO4 was present when Fe gluconate and PO4 were present in the same solution, even when the solution was acidic. it was observed that this Precipitation occurred within few hours and it was more noticeable as the day went by. I would picture the same to occur in the aquarium.

this was expected to happen, especially when Iron is not chelated. I believe some of us already had the concern about the PH and HCO3 from very beginning. I wish you could eliminate all the CO3 on all these setups. are you able to try the DTPA Iron, sometime down the road?

just for comparison, the algae and the Chlorosis

@Andy Pierce I believe the Idea behind Maq's experiment is to make sure all the nutrients are easily available in the water Colum. you are likely to see precipitations and other flaws caused by unfavorable ratios and excess nutrients in these tests. "Ratios do play an important role" far as...

Long as you know the chemicals and their % these two link is all you need: Link #1 Link #2 lets assume you want to make a stock solution while using KHCO3 KHCO3 contain 39.0533% K we are going to Mix KHCO3 in 500 ml Solution and dose 20 ml from this solution into 5 gallon RO water (18.9271...

nope, just some simple mathematic and chemistry knowledge/Skills and most calculator does the rest for you. I have further updated the post #10 I missed something earlier and updated it now. I believe this is all you need if you want to make a stock solutions, aiming target ppm, TDS etc.

for example: if you were to use K2SO4 add 1.265 gram K2SO4 into 5 gallon this will add 30 ppm K and 12.3 ppm S convert S into SO4 by 12.3 x 3 = 36.9 30 + 36.9 = 66.9 TDS = 66.9 K 44.8737 % S 18.4008 % O 36.7255 % 36.7255 + 18.4008 = 55.1263 55.1263/44.8737 = 1.228 30 ppm X 1.228 =...

@M.eremin do you have TDS meter? so what was your main purpose behind the question? are you raising the TDS for shrimps or something else? let me know if I could further help you with anything.

1 table spoon is about 15 gram KHCO3 794.23 TDS in your 5 gallon RO water

1 table spoon? are you sure am reading this correctly? you are looking at 309 ppm Potassium and 22 dkh

Ah I see, I didn't notice the names on each pictures earlier.

@_Maq_ Can you please put a Text on each picture indicating which is which?

I don't think you understood the reason behind his Experiment. its not about growing algae, but primarily focused on plants and Nutrients. Algae is likely to grow under all those 4 setups, but the amount of algae will vary in each setup and that is what people are interested in.

any possibility that you scrape off all the algae's from all those tanks and let the new one form ? this is just to compare the outbreak on all those tanks at different settings. thank you

@_Maq_ was the algae already there on the glass before the experiment started ? if not, then I would expect the lean tank to form less algae.

once you have too much evidence to prove something, it leaves no room for an arguments. I been on the same boat, I tried very hard to convince others but they didn't believe in anything until they were shown the evidence and to support that evidence, they had to do their own experiments to...

certainly you can achieve the ions with different chemicals or salts. I just wanted to see if you were just willing to test CaNO3, MgNO3, KHCO3 or K2CO3 to maintain your suggest Ca, Mg, K rather than using other salts that usually contain high amount of Chloride or Sulphates. I hope that make...

Go for it @_Maq_ Regarding my previous post, it was just an request and doesn't need to be fulfilled during this time. But, I would like to add that when NH4 is added to the picture, it can greatly benefit the plants weather the ratios are off or Nutrients are excess. I strongly believe when...

Maq, I suggest you use the standard Classic EI levels while using the simple salts such as KNO3, Kh2PO4 for N P K. I think many people would be more interested in this test when comparing with the other one. Marcel Experiment was done while using higher nutrients in some of the test tanks...

both S and Cl are needed by the plants, if you are adding 1 ppm S and 0.5 ppm Cl weekly, then you have plenty of both for the plant needs. most fertilizer don't add it because they use various different chemicals to make their fertilizers, while some of them uses Sulfur or Chloride based...

its not a myth, the fishes needs to be exposed to it for period of time before they start to decline. there are many article out there that can explain it in much more details, google is your friend. seems risky according to this long as there are plants in the tank and water is moving with a...

what you could do is make a Nitrogen Fertilizer made from Urea and KNO3 Combination, it insure lean dosing while providing the plant with enough Nitrogen. you can skip on adding adding additional P if your tap water already have enough. your tap water looks good to me, PH from the tap is bit...

@eminor instead of 26g of KCL in 210 ml of water, does this dissolve fully if you were to add 5 gram ? if it fully dissolve then try adding the following to it after fully dissolving it: 10 gram Calcium Nitrate or 10 gram Calcium Chloride if its truly KCL. there wont be any reaction or...

@Jan_H Am not sure what substrate you are using but I assume it's not acidic and rather appear to look on the alkaline side which will complicate or make the situation even worse especially if your water is already hard to begin with. The EDTA Fe might not be beneficial for you and I suggest...

one have to reach these levels using extremely excessive level of SO4. this is also found in your filter media, where there is oxidized Fe, Mn etc.

I assume one reason is solubility and the other one is unknown. maybe we should ask someone who is afraid of high SO4, i myself don't like adding S or Cl in excess as i prefer low TDS and clean water. here is what you are adding when you add CaNO3:

@MichaelJ there is nothing wrong with adding CaSo4, most people don't like too much of SO4 in their water, SO4 is much safer vs Cl though when it comes to plants, shrimps or fish, Cl doesn't pose much threat unless its extremely excess. you also get tiny amount of NH4 coming from CaNO3

Most likely they use calcium and magnesium chloride, especially if they say it doesn't raise the kh.

Ca deficiency are very rare because the plant need for Calcium isn't that high. The only time high calcium can be beneficial is if you dose high micros. It acts as a counter balance, especially if you dose high boron. Far as the plant goes, I was growing plant at 1 ppm Ca weekly. Far as you...

- Magnesium sulfate and calcium Chloride will precipitate, that milky stuff is mostly Caso4 which isn't very soluble, even though most of the Mg would have been present in the solution which is highly soluble. but since you also added Potassium Carbonate, your solution truly contain mainly K...

you can never truly make a good GH booster in a solution, unless you use NO3, Cl based chemicals for Ca, Mg. anything that add Co3, So4 in the same solution will quickly react. your best approach is to go with: CaCl, MgCl, CaNo3, MgNo3 together if you want highly soluble GH booster solution

kept the 0 KH for decade now and am confident enough to say that you are more likely to kill your stock with overdose of CO2 rather than the 0 KH. you can expect the PH to stay between 5-6 and I have never seen it crash here is a good discussion about the KH and PH: KH and plants
