I would simply use a good PC fan to blow away heat and suck in cool air. If
need extra cooling, use a house fan to blow directly to your tank.
Central AC or windows AC will run up your bill.

Your temperature should not be swing too much if you have a good heater that
will turn on when temperature drop. My tank temperature constant at 82 - 84
all year round [Northern Cal.].
Most of the tank temperature will have a great swing if it located close or
near a windows or to some heat source.

No, I live in Southern California.

OOOOH

That's what I do every year with the fans. I'm just thinking it might
actually be cheaper to run a chiller instead of two fans. And possibly
quieter too!

not a chance!!! well quieter thats 50/50 if you use good fans and set them
up right there
fairly quiet, if you use a cheapo chiller its not. both extremes are
possible.

Mark, are you saying that the A/C mod is better than an actual
chiller?
At $500 for the unit you have a good start on an actual chiller (or a
good
used one).

ive considered that one, this summer I just might endup doing it. but for
now ive been
able to get away w/o one, I did run an "actual chiller" at least it was
made to be ran on
an aquarium, then grey davis happened! and I went back to fans I do run
2 TEC based
chillers(1 external & 1 DIY iceprobe), there great on small tanks, but not
for much over
40gallons
