I get home from work today only to find that many of my favorite coral are lookng very bad. So I immediately begin running tests to discover the source of the problem, and find that my tank temperature is at 90 degrees. Anyway, to make a long story short, it turns out that my less than one year old heater was stuck on. I am not sure how long the tank was running at that temperature, but my ORA Belina is bleached, my huge frogspawn has completely closed, my green finger leather is withered, and almost all my other corals have deflated/receeded their polyps. Unfortunately, it is still too early to determine what is going to pull through. Guess it will be a long weekend of wait and see. On a positive note, it appears that all of my fish are doing well. Bottom line, with the weather heating back up, make sure that you check that all your heaters are functioning correctly. Don't let malfunctioning hardware ruin years of coral collection for you too.
