My DIY Fan bracket

[weaglereefer]

Constructed this bracket to hold some computer case fans over the rear of the tank. It's made of 1/2" pvc and the fans are held on with zip ties. Total cost for all materials including fans and power inverter was less than $30.

Nice idea... what effect did it have on your temp?

Well it had 4 on my 75 because the HOB overflow was in the way, with the 90RR I'm able to go all the way across the back.

Before I had the Reefkeeper, I accidentally dropped my temps to 76.5 in the 75G when I forgot to unplug the fans at night. Temps over the past week have had the tank sitting just above 80, but since yesterday the tank has been back to 78.5

It will be in a canopy, so it won't be seen.

I have three small fans in my canopy... they struggle to keep the temperature below 81 with the two 250w MHs and the two VHO acintics. I am able to average about 79 by letting the AC Jr. turn the lights off and on.

Where did you find the fans?

I think they were on NewEgg. They started at like $3 a piece, but went to $1.29 when you got 10 or more and had free shipping on orders over $10. So I got 10 for $12.90 w/ free s/h, lol. I think they're like 35cfm each and very quiet even when they're all on.
