My 250's sit about 6-7 inches off the water. I have a chiller which helps a lot - the best investment I have made! An 8 degree swing is a lot - I could see corals being very stressed out with that. Fish might be a little more tolerant, but it is still a large swing. I guess it also might help to define '8 degree swing'... are you talking 78 to 86? or 78 to 82, back to 78 (4 degree's up, then 4 back down)
Either way, it would help if you added some fans if a chiller is not an option. The less swing the less stressful it is on fish/coral.
