Fan Placement on 55gal - Page 5

the fans are on the same time as the light right now ( i have timers i'm just too lazy to program them), they are on a speed controller (PC 4 channel) - which I will be switching out for another controller w/ 24vdc supply all in one that I found at MicroCenter. the dryer duct would have been huge and gaudy and I couldn't find an easy solution to making a fan box, but come to find out that startech.com 40mm thin fans fits perfect inside a 3in to 2 in reducer, throw a 2in to 1.5in reducer bushing on the other side and some pvc and then some 90 degree elbows and viola! pulls and pushes air from inside the tank all while being hung discretely on the back of the tank (think of a fish tank filter).

So far it's been working , but I"m thinking for heavy CFM applications, I can do a double fan on each side.

this is the all in one control/power supply I mentioned: http://microcenter.com/single_produc...uct_id=0251807

Wow- that controller looks sharp. A bit more than I'd need, personally. I just use the variable speed adapters and set them to where I want them. I keep them running at night, too- my reasoning is that in a humid environment, it's when it gets cooler that you start to have problems with mold, etc. Good to know as well about those 40mm fans fitting inside that PVC bit as well.

And is this doing anything to keep the condensation off the front glass? And is this method keeping the moisture out of the fans as well? I'm loving this idea, personally.

interesting... as stated before pics would be real nice.

i'll be patient though.

He's got them up, Beck- one page back.

yah beck...sheesh.

So far, it's been running since Friday afternoon and i haven't lost a fan, but it's really easy to switch...I had to dremel a notch on the reduce to slide the power cord for the fan, but to replace the fan, the assembly splits in two, swap in a new fan, slide together and put back on tank.

It's keeping the glass crystal clear, there's not a noticeable breeze in the tank but I have some ideas (mostly overkill) to really get air moving around.
