#ed_op#DIV#ed_cl#well one of my heaters exploded in the tank most of the corals are not looking so good. i quickly put together a 20 gal tank and transfered the coral to it. the water is really yellow i changed 25 gals last night and am going to change another 25 tonight plus i'm running carbon. what else do you think i can do to make it better? any ideas? this is a 55 gal tank.#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl##ed_op#/DIV#ed_cl#
