    The more evaporation you have the better, it helps to cool down the tank. You are reaching critical temperatures there. Remove the lid from the sump and place a fan there to blow over the sump, this will increase evaporation and cool down the water. Can you install 2 small computer fans into the hood of the tank to blow air into the hood onto the water surface?

    Hi Gemini - firstly: That's a VERY nice setup you have there - how much is the total water volume you have?
    Secondly - as Viper has already said - EVAPORATION is the biggest key to colling your tank's water. BUT - at this stage, seeing that you don't have any corals or fish in the tank yet - I am glad that you are worrying about this now, because you WILL most likely loose lifestock once you actually have corals and fish in the tank, and the water temp's goes up THAT high.

    A normal fan over the sump will definitely assist - but it seems that the sump is enclosed at the rear as well???? So, the heat is actually "brooding" inside the tank stank, heating up the water of the sump, more rather than cooling it down.

    The water will indeed cool down, but with the sump being so enclosed, it will take MUCH longer......

    Perhaps you should device more PC fans in the hood of the tank, that actually blows air directly ONTO the surface of the water..... Also - perhaps remove the hood (if you can) for about 3 or 4 hours, and during this time, the tank's temperature will automatically drop.....
    While you have the hood removed, cut some slots into the rear of the canopy, or drill some big holes into the canopy, that fresh colder ambient air can get into the tank faster..... this all will assist in cooling the water down, and keeping the water cooler...

    It might be an idea to look at getting a chiller.

    Nice looking tank. I think you may have a problem on your hands, we haven't even started our summer yet and you are having heat issues, I think you are going to have to invest in a chiller.

    Nice setup there! Wont it also help with gas exchange if you have good clean air coming in as suppose to completely sealing it off?

    i dont have all the fans up and running yet i want to try a few thing first before getinga chiller i never had a problem wit other tanks in the same room before i would want to try this also Mega Powerful Nitrate and Phosphate Remover - DIY! - General Discussions maybe it will work and here is my hood set up with a good 6cm slot 180cm long[​IMG][​IMG]
    but i had lids on the openings of the tank to stop evaoration but removed them so maybe this will fix the problem
