I am having some weird stuff going on. I had a snail die about a week ago, then I noticed my green digi hasn't had normal polyp extension for a few days, another coral that is a softie is dieing off slowly also. Then to boot, my flame scallop looks as if it died today...or is on it's last leg at best! I can't figure it out. ALK is 6.8 again (down from 8.4 a day ago), calcium is at 390, nitrates read 2 ppm, nitites and ammo zero. Salinity is 1.25 and temp is always 76-77. Any ideas. Bring on the suggestions...perhaps my water is just getting old. I have only done one water change since I started the tank a long time ago. But, the reason for that is that my readings where always good. It has just slowly started getting bad. I also have a bad red algea out break again...which I had fought off for awhile.
