I did state in my original post that I have hard water, but didn't quantify that statement.Roan Art said:Hold a secky-decky. Alkalinity is not a measure of water hardness. It's just a measure of how acid or alkaline the water is. My pH runs from 7.4 to 7.8, but my water is fairly soft at 5 dGH, not hard.
You're right, and I don't have a reliable GH test kit yet. I was basing that statement on the amount of mineral deposits i get on anything my water touches (I hate those white deposits on the inside of my tank walls...PITA to scrape off). The first test kit I got was a 5-in-1 dip strip (before I knew better) and it registered right up at the high end (300ppm = 17.54 dGH) but since then I've learned not to rely on those dip tests.Roan Art said:No way to know unless it's tested with a GH kit.
I'm pretty sure it's hard water, but I'll definitely confirm that with a good test kit before starting a cichlid tank.
