This tank took a turn for the worse. The sump wasn't built the best and the baffles broke, as well as the ato reservoir. I have had the ato part fixed for a while and fixed the baffle yesterday. During all of this there was an ich outbreak. I decided to go the hyposalinity route which resulted in killing off all the snails and the fish :-(. It has been empty for well over a month now and its time to stock back with fish. They will be here Thursday, and I went back with what I started with (almost) line spot flasher wrasse, carpenters flasher wrasse and a yellow eye kole tang. ATTN TANG POLICE!!! A YELLOW EYE KOLE TANG IN A 40 GALLON!(blast away :-P) other than that its going ok. I'm sure after leaving three sump dry for a coulee days I'm going to have another green algae outbreak. It cleared up, I fixed the ato, it came back, cleared up, and now fixed the baffles. I haven't been ghost feeding lately because I added another 8 lbs of uncured tukani rock about 2 weeks ago. I'm sure there wad enough die off from the rock to keep the biosystem alive and well. The curve 5 skimmer has proven to be quite the beast! It always has a thick head and I'm really liking that.
