KNO3 replacement

[omartinez]

Hi,

I'm new to this forum and have one year of planted aquarium experience, not much .

I want to start with EI and started looking for the compounds then i hit a problem.

In my country, KNO3 is not easily found, actually none of the compounds are easy, i have called a lot of places and no luck. I tried to import it from USA but for what i read it not allowed to import outside USA, or is it?

anyway, there is a sustitute for KNO3 that i can import/use?

Welcome omartinez

I encountered the same problem. I gave up looking in gardening stores (visited more than a dozen) and went for lab grade (which is basically paying a lot more for the same product, given the use I'm giving to the compounds). For some reason in my Country urea [CH4N2O] seems to be the main source of Nitrogen, at least in gardening stores.

I don't understand why exactly urea is a problem for aquatic plants (maybe due to the sudden release of ammonia [NH3] in contact with water) but it seem to have some issues that harm both plants, inverts and fish.

Pepetj it's me, hylik ...

I saw EDTA iron on the store i told you yesterday but not macros ....

It will be difficult to start EI without that ferts....i will keep looking for solutions...it will be a great help if there is a replacement for KNO3 so we can import it safely

I know a fellow aquarist here in Arizona who's using 'Miracle-Gro All Purpose' to fertilize his planted tank. He doesn't have any problem like algae or fish dying - the tank is heavily planted. Miracle Gro is water soluble and it makes it easy to apply in dry form. Is this product available in your country?
