mine is down to 86 now. Hopefully I can get it back to 81 by morning. I think the 400w in the sump will stay off tonight.

80-82. Not to bad cause it was 35 today :eek: I'm kinda in a basement and I use 250w halides. I could probably put a fan on the sump if need be. I guess no swing is ideal but Im sure the shallow tropics rise and fall a small amount or no?

i came home to temp of 88f at 11pm at night :(

:eek: Like Deb says, "wholly crap". Boy thats warm. Hard to believe its not hard on the tanks residents. Guess it speaks volumes for keeping ones tank over 80 all year, so the spikes are not a great change to the warmer side.

Being a spoiled oldbrat,It sure is nice having AC. :mrgreen:

I guess that tank temperature is one advantage of living in Northern Alberta. We had to turn on the furnace last night.

Yeah mine shot up from 79 to a whopping 86 yesterday :eek:

I just came home from work and after having the fan blow on the water surface of the sump overnight, the temp has now drpped down to 81.

I'm thinking that maybe I should drill a hole in the side of my roomates small bar freezer, then run a line of my tank water through it to :cool: things down :mrgreen:

cheers, sumpfinfishe

I left home this morning with the temp at 81.2. Hopefully it isn't near 90 again today. I left extra fans on...... :rolleyes:

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.

Ahhhh, the joys of having one's tanks in the basement, and not fooling around with MH. :eek:
