Calcium ?

[Ruth]

I can only speak from personal experience and I have to say that one of the best peices of equipment I have bought is my calcium reactor. It takes time to dial it in but once done it has been great. I have previously used kalkwasser and I know that people have great success with it but I really stuggled to find a balance with PH. I have to say at the time I believe that I had low magnesium just didn't know enough to test for it.
