Best way to get missing nutrients
Hey everyone I'm new to the planted tanks but am learning daily. I'm on a well water system but we run a water softener and it strips alot of the needed minerals out of my water. I tested the KH,GH and calcium levels today and it seems that my KH is always through the room at 400ppm and my GH is super low at 60ppm. So than I tested my Calcium and it was 30ppm or like 3* if that makes sense. My plants seem to be hanging on but I feel could do better. So my question is how do I add calcium and magnesium to my tanks to bring up my GH? My Nitrate levels are 40to 60ppm , Notrite and ammonia are both 0ppm. My PH is always through the roof at 8.4 but it's never seemed to bother my cichlids.
