    Are you sure....positive that your tempature indicator/monitor is working right...i had my pinpoint fail once on me.What about fans?I have 5 fans on my little tank...works very good and quiet too.

    Once a volume of water is up to temp it resists change because all that water is a good heat sink. Simple overnight wait would not likely make that much difference unless the room is several degrees cooler. Fans will do the trick as Derik pointed out

    I have a large fan on the back of it, but it only turns on when the lights come on, allthough i can easily change that,
    Derik - i have two digital temp monitors, and they both read the same , one in the sump and one in tank

    I'm thinking about purchasing a USED aquacontroller I unit off RC for 185 comes with brand new PH probe, temp probe, aquanotes 3.0 software 4 control modules, and the computer cables

    oh and what kind of fans do you have?I have 3 x 4in computer fans and 2 x 3 inche computer fans...all plastic fans 3 of them are plugged into a 1000milliamp ac to dc converter and the other into a 500 milliamp converter....i have a small little 36 in tank and 2x 250 w halides 8 inche over the water...10 hrs a day and my temp NEVER goes over 79C at the most...Maybe one or 2 other little fans would do the trick

    I have a honkin full size behind there for now, becuase the fan that was back there died on me, and i had to pick something up from CTC on a sunday, its way overkill, but i haven't had time to rig something else up
    Its a honeywell 12 inch turbofan

    I read this idea elsewhere.... How about placing ice cubes in baggies and letting them float around in the tank. Worth investigating.

    That will work but unless your going to keep after them all you will do is see an ever changing temp in the tank. Floating ice in bags or full frozen 2 liter pop bottles is really an emergency action

    It's quite possible that your digital temp readers are giving you a wrong reading. I have one in the sump and it's reading 82 and i have a floating type reading 78 in the tank.
