I don't use CO2 yet as my tank is immature, and I have been told and read it is best to get the plants established first. Also I'm only 2.8 watts per gallon, not bad but not huge.
I really only use Flourish, Excel, Root tabs, and a little iron.
Can someone translate these to English and how do I supplement them?
KN03 - potassium nitrate?
KH2P04 - Potassium hydrogen phosphate?
K2S04 - potassium sulphate?
What do I need?
