I see. I was actually only planning on putting the main pump into the UPS but now that I think about it, maybe I won't, because (a) it looks like it will be relatively costly to get a UPS, and (b) using the UPS will also take away the safety benefits of the GFCI that it's plugged into. Oh well.. will just get a battery powered pump.

Really? This is quite a surprise! I would've sworn that brass would be just as ineffective as steel. Are you sure about brass?
Ok then.. will get some brass L-Brackets. Mind you, I don't know what the actual pendant is made of - I would suspect stainless steel. And I have a feeling it has just standard metal screws in it. Should I be worried that it may rust?
As an added precaution, I'm also affixing a couple of lengths of nylon-coated galvanised steel strapping around the pendant. (The stuff that plumbers use to attach pipes to walls) Should this be okay in there, or should I get the standard galvanised steel kind? I don't know if this nylon coating may melt under the lights.

Hmm.. ok. Good advice! Now.. where does one find 120V AC fans? (I'm assuming these would look identical to the standard small'ish computer fans) Also, should I do something special with wiring these fans for use inside a saltwater aquarium canopy? Any safety or corrosion issues?

This seems to be a controvercial topic! I have had people tell me all sorts of differing opinions on the number of fans, their locations in the canopy, and whether they should be blowing air in or taking it out.
I was planing on having three or four fans in the back of my canopy (since the back side is open). I was going to have two fans (one on each side of the back) blowing air in, and a fan (or two) in the middle sucking it back out. I was advised this at my LFS and, admitedly, it did sound sensible.
Now, if I only have a couple of fans blowing air in from the back of the canopy, where will the hot air escape?
I was also told that it may be just as effective to have fans installed on my sump instead of the main aquarium, although this doesn't sound logical as surely the lights above the aquarium is what is causing the heat and it makes sense to have something attacking this issue directly rather than trying to cool off the sump. Is this correct?
Thanks again for the help!
