    How much Potassium Phosphate (KH2PO4) for 300 litre heavy planted tank?

    Hi everyone, I'm currently preparing 1 teaspoon of KH2PO4 ( 7.66 grams) mixed in 500ml water and dosing 50 ml, 3 times a week. Is this enough Phosphate for a 300 lt heavy planted tank? If not how much more should I add? Thanks...
