I have a 125 g tank that I setup about 3 months ago. I have cycled the tank and have 5 fish in it now. I have purchased some zoanthids that have not opened up for almost a month now. I recently read that they can be sensitive to high alkalinity....which is one area that I have been high. My water parameters are as follows....sg 1.023, Ammo 0, Nitrite 0, Nitrate 0, Calc 560, Alk 12 dkh(recently down from a high of 18 dkh), Phos 0. I have been changing 10 gallons of water every day for about 10 days now and my alk is coming down. I am using compact flourescents 12,000k with blue actinics. In the last few days my zoanthids will open up about 1/3 of the way for a while then close again. They don't appear to be dying, just won't open up. I also am having problems keeping snails alive. Any suggestions would be appreciated.
