Man, I just use 250's over my 75 and I'm constantly fighting temps on that tank, and that's with the temperature rarely exceeding 25. Two Icecap fans in the hood, one 8" blowing onto the sump seems to keep it around topping out at 28 or so (I'm using C. I usually convert my temps to F for the benefit of all you antiquidated Fahrenheit folk, but this morning I'm taking a stand and using C!!!!!) Of course three fans over the 72g and three fans for 75 makes for not much except a lot of high blood pressure some days (I love my hobby ... I love my hobby ... I love my hobby.). Mind you some days I'm able to tune out the fan noise. The 20g, with no fan, is topping out at 29.5. These are when the temps outside are in the mid-20's ... I am so screwed if the temps shoot past 30. I might still put some pop bottles filled with water in the freezer, to drop into the sump as a backup plan for those days.

Keeping the window open has helped the daytime temps, but now I have a problem with my one tank DROPPING to about 24 at night. Sigh ... the other two seem to keep up but not this one, I guess I have to actually put a BIGGER heater in there for the summer (what an incredible revelation).

Nope, summer isn't generally a happy time for my tanks. I don't know how everyone else gets away without any fuss. And I'm contemplating a move to 400's this summer .... I wonder if I ought to wait until fall. We'll see.

Icecap fans are nice, but when they step up to 110cfm, they really do sounds like a jet airplance turbine winding up.
