I use it as K supplementation in my occasionally high light tank. Sometimes P and N levels rise higher than I'm comfortable with, so I burn them off (don't dose). Since I've seen signs of K deficiency when doing this and it's apparently nontoxic to inverts and fish, I now dose KSO4.

29g high tech, 10g low tech halfmoon, and please see my 5g crescent journal.
