So water testing isn't my strong point. On my planted tanks, Ive gotten to where I can look at the plants and get a feel for how things are doing. I guess I thought I was already to that point with corals, but I now see I was wrong.
I tested yesterday. My alk has always been a little low, but just before PWC it was down at 7. Ca was down at 360 and my mag was down at 1140.
This all seems a little low to me. Sparky, despite my wishes, convinced me to order some two-part. I thought my corals were doing and growing well, but if those numbers are that low then I suppose theyre not doing as well as they could be, huh?
So my question. Kalkstirrers and/or Ca Reactors can help to automate this process. What about the magnesium? do they help maintain that too, or is the only way to do that via dosing?
