    cooling help

    I've installed 4 fans which have been running nicely for the last 3 weeks but the temperature in my tank has still been creeping up to 82F ... does anyone have any suggestions of how i can lower the temp and keep it down to 79ish ?

    Aside from buying a chiller you might try:

    Moving your ballasts out of the canopy if you haven't already (or if it's possible).

    Get an old heatsink from a computer parts place (or 3 or 5 depending on the size) and attach them to your ballast, aim a fan at the heat sinks.

    Add more fans / faster fans.

    Clean your existing fans. If they worked fine for 3 weeks & you're not having a heat wave, maybe they're dirty...

    You might also want to check your kit, I've heard that some equipment (pumps, etc.) can produce more heat if they need cleaning but I don't remember where I read that so I could be out in left field.

    Turn down the AC in the house

    Cheers!

    I open the basement window every night after sun down and fill the basement with cool air and run the furnace fan. I close the windows during the day and it seems helps a lot to do this.

    I've found that if you start running your fans before your lights come on it also helps.

    4 fans are installed in the canopy, 2 blowing at the surface and 2 across the top of the surface towards the open back.

    the problem is that i'm on the 3rd floor of an appartment building without air conditionning so it gets pretty warm in the summer.

    If you don't pay for water, you can run a loop of tubing through your sump and out into a drain. Leave the cold water on at a trickle when you need the cooling effect. The longer the loop of tubing, the more cooling.

    In the summer, I set my temp for 26 to allow for a degree of extra rise in temp. In the winter the temp is set for 27.
