So because of Sandy my home lost power for 8 days and though I tried my hardest to keep my fish alive in the end they all died. From my fave clown fish to my emerald crabs, all gone. Two days ago when we finally got power back I decided it was time to clean out the mess. I scooped about all the casualties and took the opportunity to redo my rock work. Sine the water was so foul smelling I took out about 80% of the water out and replaced it. Today my water is still very cloudy and the rocks also look dusty. My ammonia is 4 ppm. I was wondering if anyone could help me solve these problems. All other test results are normal as well as salinity. I'd really like to get my tank back to where is used to be.
