Tank stock is: 1 frogspawn, 1 torch coral, 3 duncans and one small frag of SPS - Birdsnest and the rest are soft corals.
Calcium level is 390ppm. I'm told that Ca levels should be 380-425ppm - what is the advantage of higher calcium levels? I'm assuming that having it higher ensures that there's a larger buffer, so that if uptake of Ca is high, the chances of hitting the low point is prevented.
