yes bro think a lot of reefers are converting to fowlr or more hardy corals, all thanks to the rising electrical cost wow if 30 deg will be damn stress for the corals but luckily urs most of the time is between 28-29deg, still a bit high though but not as bad. I actually removed some of the partitions in my sump tank to make it more spacious and better cool off as well. won't be going or corals at the moment, maybe few months down the road see how.
