Hi, I have a friend that uses (NH4)2SO4 in his planted tanks. I try to find it but I not found it.(He lives in Mexico and I in Puerto Rico). Why bulk fertilizer dont make it or it is easy to found in USA???

Left C said:Also, are you planning on staying with Seachem's fert products or do you want to convert to much cheaper dry ferts? Should you want to switch to dry, but mix your dry ferts' solutions so that they are the same strength as Seachem's; here is a bit of info about the macros.

"Using – Mixing Dry Chemicals for Seachem’s Dosing
Seachem’s products are a little expensive, but they are very good. I know some people would like to cut the cost some and use some of the dry fertilizers that are available.
The following dosing solutions will be practically the same strength as Seachem's macronutrient products according to the online calculators. You then go by Seachem's recommended dosing amounts on the calculator.
Dosing Solutions
- Add 62.2 grams or 11⅛ tsp of KNO3 to 500 mL of distilled water for F. Nitrogen Substitute
- Add 3.5 grams or ¾ tsp of KH2PO4 to 500 mL of distilled water for F. Phosphorus Substitute
- Add 51.0 grams or 8½ tsp of K2SO4 to 500 mL of distilled water for F. Potassium Substitute*
*(This amount approaches the maximum solubility of K2SO4 of 12 grams per 100 mL of distilled water. You will probably need to shake the container each time prior to dosing.)

Brian20;47323 said:I know this can be lethal for animals, As you know I make solutions from dry ferts, so I can make a solution of this to make it less lethal. Or I can make a solution of it with KNO3 like Seachem Nitrogen. Im just curious tu use this. The problem is that I cant found it, I will try Garden shops.
Brian20;47337 said:Dont worry, I never killed a fish in my experiments wit ferts (Math never fail) I know that a lot of people kill fish with accidents or because not read, but when you not have a lot of money to spend in fish (like me) you will care of them. However I have 17 planted tanks so I have 3 or 4 without animals where i can make my experiements.
