ok I may be way off base (wouldnt be the first time) but I think the water temp can be solved fairly easy. Please dont laugh, here is my thought:
A large Res with a simple cjiller should keep the water temps in check.
Let me explain, I have a 125 gallon salt water tank, I use a small chiller to keep the temp down so my salt fish and sea life stay happy. Even with a hi output pump ( tank is running a little giant pushing 600 GPH, the temp stay within a degree or 2F of constant. this is with five 6 foot high UV output floresent bulbs shining in the tank for a minimum of 10 hours per day.
So since we seem to only be using about half the GPH pumps in WC and with a 30 gallon tank with chiller I would think the temp variation would be almost nothing.
Just trying to help
