My normally very healthy green star polyps have completely closed up in the last day or so -- none of the polyps are extending. This is now a fairly large colony (roughly 7-8 inches in diameter, with several offshoots), growing over several rocks, which has been growing like crazy.
All of the other corals and livestock in the tank look great (Xenia, zoos, palys, shrooms, torch, branching frogspawn, maze brain)
Any ideas what could cause this, but not affect anything else?
Just ran a few tests:
Nitrates: between 5-10 ppm (about normal)
Nitrites: 0
Ammonia: 0
Calcium: 380 (a little low)
Alk: 3.2 meq/l (about normal)
Temp: 82 (normally runs around 80 -- could this be a problem?)
PH: 8.2 (normal)
SG: 1.025 (normal)
This is a 90 gallon tank with a 30 gallon sump. Auto FW topoff and 1.5 gallon per day SW changes (automated). I did just switch to Seachem salt because I'm told the Alk is much better than the Oceanic I was using -- but there can only be about 4.5 gallons in there at the most.
Thanks!
