I dosed with Purple Tech for the first time this morning, and, when I went to test my calcium, it was off the charts, literally. I have the API test kit that tells you to continue adding drops until the solution turns blue. The chart in the booklet went up to 26 drops (which was an indicator for 520 ppm). When I got to 26, the solution was still a little purple as opposed to blue, so it looks like my calcium is at 520 ppm or even a bit higher.
I don't have any corals in the tank yet, but is this much calcium bad? Is it livable for corals and other inverts?
Also, should I continue dosing with Purple Tech as the directions indicate?

If you are planning to keep corals, especially SPS or LPS, then this might be a good read for you.

if you calcium is really that high, i would not add any more.
