That's a fine plan, assuming you believe the calcium test result. If you did not add a lot of calcium somehow, I'd be suspect of the value since normal IO won't typically have calcium that high.
Newbie here, so this question may seem obvious, but here goes anyways. My tank is about 5 months old, 40 gallon breeder. Crushed coral sub straight. I have a lion, a fire angelfish, a striped sail fin tang, 2 black ice clownfish, a chocolate chip star, and 2 hitch hiker crabs, look a lot like emeralds. This is a "get my feet wet tank" and better under stand saltwater tanks and all that live inside before I get a 125 gallon. My question is this, should I start doing the 3 tests, alkalinity, calcium, and magnesium now along with keeping the levels correct to get in the habit of it, or is there really no need for that at this point if I have no corals?
Thanks
