Paul... depending on your temp in da room you will heat your aquarium quite
a bit.

I would mount them blowing in. The reason is that they can blow directly
onto the surface of the water, and they will last longer, being subjected
to
less humidity and salt water mist.

On my new 180 I plan on mounting them one each end of the canopy , blowing
in horizontally (2 Icecap variable speed fans).

If my canopy was constructed differently, I would put them in the top,
blowing down onto the surface of the water.

I have a 125 gallon tank with Compact Flourescent light underneath the
canopy. I have purchased a couple small fans, maybe 3 inches diameter
or so. I plan to plug them into a timer and run them during the day
when the lights are on. My question, what is the best way to mount
these?
I assume one towards each end but do you want them blowing into the
canopy or out of it or one one way, one the other?
Most of all, hwo do you physically mount these under a canopy? I know
I'd mount them towards the back but they are a square with just black
plastic and a screw towards each corner holding the front onto the
fan. I just can't figure out if I need a bracket or what to use.
Thanks for any help.
