What will the effect of limestone be in already hard water?
My tap water has kH of 7-8 and gH of 11-12, pH 7.8. I'm starting a new tank and looking around for some rocks. I was at a landscape place the other day and found some nice stuff but they didn't know what the source was. So, I don't know it they are limestone or not.
If they are limestone or some other carbonate source, how much of an effect will they have on my hard water?
I'm testing some samples but I really want to scape this tank and get moving!!!
