Hmm...interesting suggestions, thank you for the advice.

Myka, I will try to do the Carbon changes more often. I don't actually use that much in the reactor, maybe 3/4 cup of HC Carbon. As for things that co-incide with the issues...not really...the timing is just an approximation of how long it takes to go sour.

As for my salinity...I do have a hydrometer but I use a refractometer and have done so for about a year now. I will look into re-calibrating it just in case but I have a second tank (a nano) that doesn't have this problem with acros that I measure with the same refractometer.

Could my problems be somewhat related to having softies in the tank? Maybe more carbon, more often will take any possible toxins out better. I would think that if this was the issue, the other SPS would show the problem, but they don't.

I will try to up the Mag some and also do more water changes in case my Nitrates are the issue. Has anyone had good luck with the nitrate destroyer from Tailor aquatics?
