I will be starting to use the EI fertilization method on my tanks. I have seen that I seem to have some low light tanks and therefore, have read that I would only need to dose half of the amounts of compounds for this method. I will be dosing the 70G with 116W of 6500K lighting and 2-10 Gallon tanks with 30 Watts of 6500K CFL lighting.
Is there a relationship between the percentage of total nitrate in the KNO3, or the percentage of soluble potash in K2SO4 or the percentage of phosphoric acid in KH2PO4 with the dosage? Would those dosage be for compounds that are 100% (pure) and therefore, the percentage of present N, K2O and P2O5 would have to be taken into account? Or, would I just need to follow the amounts of each compound for the EI fertilization method?
Guaranteed Analysis (minimum):
For the KNO3, there is 12% total nitrogen and 44% soluble potash (K2O).
For the KH2PO4, there is 46% available phosphoric acid (P2O5).
For the K2SO4, there is 54% soluble potash (K2O).
