What sort of problems have you guys experienced with high magnesium levels? I've lost several acros recently and it was not long after raising my mag levels in an attempt to combat some bryopsis that popped up in my tank. I also saw some tissue recession on one of my monti caps and another monti cap go into rapid decline (though that seemed to start before increasing mag.)
For the last day or so my two toadstools have seemed a little freaked out, though they seem to retract and look unhappy on a regular basis for no reason anyway. The rest of my corals, clam, fish, and inverts all seem fine.
Other things that have changed recently:
- started running GFO and carbon in a reactor
- added some iron supplement
- put a new sand bed in (the old one went out a couple months ago)
The other parameters I've tested (salinity, calcium, alkalinity, temperature, pH, and nitrate) are all normal. So I'm thinking it's probably the magnesium but possibly contamination from the sand? Before adding the sand I washed it with a garden hose, drained off as much water as possible, and added a little Prime to combat any residual chloramine. I've been doing frequent water changes since the problem started. That seems to be helping.
Any thoughts or suggestions?
