I need to raise the KH & GH in our pond. Our public water is on the soft
side and we have been having constant rain. The GH is usually at 120ppm and
KH at 80ppm. This morning the GH was reading 50ppm and KH of 40ppm. This
afternoon the KH is around 80ppm and the GH is still at 50ppm. The plants
are letting me know that they aren't happy but the fish seem OK, so, far. I
know I need lime for the KH and gypsum for the GH. And, I know there is a
difference between dolomitic and dolomite limestone, but which one is the
right one for the pond? I will be going to Home Depot, so, what do I need
to get and how much. Our pond is around 2400 gallons. Thanks.
