Default Potassium


I see sulfate recommended, I wonder why. I have lots of stuff in my
water already, the only export capability I know for sulfate would be
conversion to H2S, or water change.

Why not nitrate, the plants could use it, or carbonate, which the
plants could use, or chloride. people are forever recommending adding
salt to the water, presumably for the chloride ion.

so, why sulfate?
