That doesnt really work as an answer though. Sure you could say that me tearing apart the display to remove the MASSIVE amount of bubble algae is what caused the bubble algae in the first place..... Well.... No... You cant say that, although it appears you are trying to.
Anyway, I will try to check potassium when I can afford to. Other then Floyd having success without adding iron, does anyone have anything to add on the subject of iron dosing? Any positive or negaive results with dosing and how much you dosed?
