Well guys I lost two of the 3 rays I had. It was an ammonia spike. So needless to say last night really sucked. I did do a 40% water change last night and added a ehime canister filter to the other end of the tank. The stuff I read on the daily here and other sites came back to haunt me. The biggest of the three is still doing well this morning so i hope it gives me some time to finish my other tank these next three days. Any suggestion on media for my sump other than bio balls, which i have plenty of?
