Fans in Canopy/Stand

[dubkie]

So my temp keeps rising and I think I need to add fans to my canopy and stand. Here is the question - Do I position the fans to pull hot air out or pull cool air in? Thanks!

you can pull air out of the canopy if your intake is low and can move across the tank. in the sump you want it to blow on the water. this will increase evaporation which is what cools the water

Just a thought, but pulling the warm/moist/salty air out of your canopy via a fan will probably decrease the life if it much more than pushing fresh air through it.

yes but most of the heat in the canopy is from the lights. if you remove it first then you wont have as much evvaporation in the canopy. and you dont have the chance of blowing bust or a flying bug here and there in the DT. in the sump you would be cooling and promoteing evaporation and if you get a floater in there the baffle or foam filter should stop it from getting in the DT.

I am with eagle. I'd rather pull the already convected heat out of the top of the canopy and replace a fan than push air in the canopy. Which means your are now mixing the hot air in the top of the canopy with salty air at the surface of the water and then blowing across expensive lighting. I'd keep my surface evaporation cooling in the sump.

Not for everybody, but this is why I run open-top canopies =)

What type of fan would you use? I'd love to have something like a quiet PC cooling fan pushing cool, dry air into the canopy and forcing it up out of the vents on top. I don't know how I'd hook that up, though.

Sure you want to blow salt spray across those lights?

The fan would be above the lights.

PC fans are cheap to replace...not so much with your lights.

Mount the fans blowing out..I doubt your canopy is air tight, plenty of fresh air will make it's way in. The ones I put in my canopy even have little LED lights on them for a little moon lighting action. So I leave them on for a bit after the mains go off.

Do it like it's done in your roof: Fans pulling the air out.
