Thanks Frankie. It worked out really well for frags and all the algae is finally gone after I put in the clean up crew and the tang.
Thanks Ratpack. I expected the heat to be a problem so I insulated the garage door, which brought the inside temp down about 15 degrees. I am able to keep the tank temp below 81 with just 2 fans on a controller so far and we've already had a week of 100+ temp outside. So I think I'll be ok. I do have a Deltec Eco Cooler if I need it. The major difference between me and you in SC is that it's mostly dry heat out here. With the humidity in your area, evaporative cooling won't work as well.
