What to buy to dose Potassium

Django · 02-09-2013, 12:54 AM

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.

K2SO4 is used for straight potassium. I have some but rarely use it because I get plenty from my KNO3 and KH2PO4

I use K2SO4 straight. There are online calculators to tell you how much to use. http://calc.petalphile.com/
