Well.... I'm scratching my head

Got the Aquacontroller hooked up and the temperature in the tank was 83 without the lights running. The house stays at 78. Decided to test the lights out overnight (only 1/2 are hooked up). They brought the tank up to almost 90 degrees.

Still have to plumb the chiller - this should eliminate the friction from having the main pump throttled down. Hope it is enough.

This is the first time I have delt with heat issues like this.
