Yes the water is cloudy. (It happened while I was away this week). I have a 50G tank. Its now about 3 months old. I did the full cycle, then added 2 fish, waited added 2 fish, waited then added the 2 corals about 2 weeks ago. Unfortunately one of the fish in second batch had ich and died. I have been battling a ammonia spike to .5 since its death 1 week ago. I had it down to .25 to 0 before I left, but now it is back up. I did a 10% water change this morning. I just checked the coral is still hard. Yes my sand is real sand. I live in FL and it was taken about a 1 mile out, we didn't like the look of the sand our LFSs had.
Thank you for the responses.
