[reefburnaby]

Hi,

The worst I have seen my reef tanks go was about 83 F. This is usually in July when we have two to three weeks of continuous hot weather with no wind or rain in between. You know when it is hot when smog starts to build up and the temperature rise to about 32 C at 6 PM. My reef tank is on the first floor - my second floor can bring fish tanks up to 90F....

At that point, we run the lights in reverse lighting (i.e. lights on in the morning...rather than evenings). Its only really a problem during 3pm to 8pm.

Its not really a big problem in Vancouver...just opening the canopy lid usually fixes the problem. If have mushrooms, Xenias or toadstools...they are usually the first to tell you when you start having temperature problems (or water problems for that matter).

Imagine operating a reef in Phoenix...50C is normal there.
