Hi Calcium?

[Goodersgold]

Hi my calcium level is fairly stable at 520 -525. According to were you get your information from this can be acceptable. With reference to BRS parameters they recommend 380-450ppm. Ph 8.2 dKh 7.5. Nano reef 40 litres with 2 clowns and a few LPS and Softies. Should I worry, or do something about it. I test once a week?

That level is fine. I would not do anything about it.

Thanks Randy, what range would you suggest?

400-550 ppm calcium is generally fine as it is not usually a limiting factor for coral growth. Even higher just seems to increase chances of abiotic precipitation of calcium carbonate, but not as strongly as a pH or alk rise.
