Although I am not new to saltwater aquariums, it's been 5 years since I have had one up and running. I just put up a 29 gallon tank and I am working through the cycling process. A few questions have come up, but some background info is here for you: I had a 90 gallon for 5 years, when i tore it down i let all my live rock dry out (essentially killing all the liveness!) When i set up my 29 gallon, i used many of the old rocks. After a few hours, the water immediately started getting cloudy and yellowish. My theory is that all the dead stuff in the holes in the rocks actually started the cycling process. I tested the ammonia and nitrites and they existed and were low. That was 3 days ago. On day 2 i added live sand and of course it's still pretty cloudy. So, 1. Do you think it was the rocks that made the water cloudy and 2. will the water clear up on its own after the cycle? I just cannot remember this happening to me the first time i set up a saltwater tank, so thats why i just want some advise! Thank you!!
