What to buy to dose Potassium
I have a 10g tank, planted, low tech. I spotted pinholes on at least one plant and I want to dose Potassium. Other plants just don't have the old git up and go and are actually not doing very much, except for the Sword.
I am currently using Flourish Comprehensive and Equilibrium. I should find out what's in the Equilibrium.
Anyway, if I dose KNO3, I will have extra nitrates which I don't want. The other one is K2something - I forget. So I guess I buy the second one, right.
Any questions, comments are welcome. Thanks.
