Chiller nescessary?

[lastlight]

I've battled temps when I've had tanks on the main floor. The thermostat in the living room often reads higher than 28C on the hot days. I've used the film on my windows to keep heat out, run window AC units which are noisy and manually operated, tank fans and even a chiller. The fans worked on the tank with a single halide. The chiller worked great for two and I had it plumbed through the floor to release all that heat in my basement. Burning all that energy for the chiller and having so much resting on its operation drove me nuts though.

Since switching to LED however and installing my sump in the cool basement I've been enjoying a tank that needs heaters to maintain 78F when my living room is 28C. Previously I ran 250W halides over these tanks.
