Glad to hear it. Just test PH periodically, if it doesn't rise to what your tap water level is or continues to drop then try a bit more argonite.
I used a big handful and left it in the tank so it's easier to take out if I need. I'm debating if I need to buy an alkalinty test. My tap water is so high in ph that you'd almost think it's hard but not for sure. Anyway I'll keep my eye on it but I'm hoping the tank doesn't rise quite that high.
