Hi
ive just bught some GH booster,and have added it to my tank 1/8 tsp per 100 litres.
Thing is,its made my KH rise by 1 or 2 dKH..
I know it not a great deal,but why is this happening?

KH is the amount of CO3 and HCO3 ions in the water. As GH Booster contains neither of these two (well shouldn't anyway) then it shouldn't affect the KH when added.

Well that was my understanding,that the calcium wouldnt make the KH rise,unless it was calcium carbonate,but im sure gh booster contains Calcium Sulfate.
Ive tested KH again today and it seems to be comming down a bit.....
