I was just wondering what K2SO4 does to the water?

I know this is 1 product to increase the potassium but how does it affect the chemistry of the water? That is the ph, gh, kh?

I am just trying to understand the affects of ferts on the water chemistry. K2SO4 was the only 1 had trouble finding info on.

Being a salt made up by a strong acid (H2SO4 - Sulfuric acid) and a strong base (KOH - Potassium hydroxide), K2SO4 doesn't alter pH.

Since it doesn't contain Calcium nor Magnesium it doesn't alter GH.

Since it doesn't contain Carbonates nor Bicarbonates it doesn't alter Alcalinity (KH).

K2SO4 will add K+ (that's what we want) but also SO4--.
Luckily SO4-- is quite a neutral and safe ion that doesn't give troubles unless in very high amounts (above 150-200 mg/l)

K2SO4 is therefore a fairly inert molecule; but don't forget hanyhow it is a salt.
So it's addition will raise Conductivity.

For this reason we don't have to overuse it and add just the amount needed

Fabrizio.
