Really starting to hate SPS

I think it has been well experimented/accepted that too high temperature causes the coral to expel its zooanthelle. I don't know about rapid temperature swings...but high temperature is certainly bad.

Absolutely agree. I've seen tanks that go up inthe mid 90s and lose most of the corals. Mine never topped 89, but it did swing 10 degrees daily, for almost 2 months.

2X 250 watt (or 200W not sure) heaters not sure if they turn on or not I can't see them but I don't see any temp swings
