SueT must be using Oceanic salt. I use Instant Ocean, so it's naturally very high in alkalinity and depressing low in calcium. I also use a reactor, and because the alk and calcium are so poorly mismatched, I tend to run my alk around 12-12.5 and calcium around 375ppm. I've started dosing calcium to bring things back into balance. I've also considered doing the Oceanic/IO mix. Magnesium tends to run around 1400ppm.
Actually we use Instant Ocean. Always have, always will. My alk runs fairly steady ay 9.3 and I don't supplement it at all besides the kalk drip.
