I finally got the power back since Saturday. I have a battery air pump but since the tank is in the basement the temp dropped down into the low 60's. My RBTA died & what a smell. corals especially zoo's & paly's do not look good. When I tried to take out the RBTA it came apart in little pieces, all over the tank. Siphoned what a could get & did a 30% water change. I would not keep another BTA, it's just too sensitve. I will do another water change around 10-20 % depending how the corals look. The one coral that still looks good is the Tyree war coral. Might be time to get a back-up generator save on food & corals spoiling.lol I quess now is a good time to set-up my 80gal cube & wait for it to cycle & transfer every out of the 30 gal cube.
