Last night i picked up a new thermometer and apparently the temperature was 88 degrees so I'm definitely glad I caught that bad thermometer. Not sure how the clowns survived, but they still seem to be doing well. I'll be picking up a new heater too just in case. For most of today I've been able to keep the tank between 78-80 degrees. Also after I get this all sorted out, I'm going to start adding some corals. I really like the corals that flow in the current, but I don't really know much about corals or what corals I can grow with my kessil a150w so I would love any recommendations.
