    I really built this evaporative chiller for my blackworm tank but here in NY it is almost 100 degrees now so I transfered it to my reef for a while. It chilled my worm tank down to 65 degrees but that is only about one gallon.
    I will see how much it chills my 100 gallon reef. If it works I will put this back on the worms and build a larger one for the reef.

    Very impressive, can you give us more details on how it works?

    There is a fan at the top right that blows air across the plates as the water cascades causing it to evaporate faster, cooling the water. There is at least one of these on top of all office buildings to cool the air conditioning water. The water exiting is 1/2 a degree cooler than the water entering.
    It is probably not large enough for my tank but it is an experiment and I built it for my worm tank. If it works at all I will build a larger one and put this back on the worms.

    Here it is over my worm keeper before it was actually completed.

    nothing wrong with that design, i have seen some uitilizing porus sponge inbetween the layers and this allows a more even cooling action..

    just be mindful of salanity fluctuations and i would definatley use an ATO when using this type of device, testing salanity every 2 days or so...

    well done good job...

    Is that in Fahrenheit or Celsius? Celsius, then its worthwhile.

    But you need to ensure that the sponge does not go biological.

    wow thats awesome, but how much evaporation does it cause? how much water do you top-up per day while running that.

    A Nice simple yet eligent solution. As Riaanp asked, it the 1/2 degree drop in celcius or farenheit?

    It's farenheit. There is an ATO also ,it's the black thing to the left of the chiller.
    I am not concerned about the salinity or water levels. It's automatic (and the tank has been running for 40 years so I'm good with that)

    Before I switched to LEDs I used to have to put in frozen gallons of ice, I no longer need to do that. I don't need a chiller either, this is just an experiment. The tank was 82 degrees yesterday, now it is 80 degrees, so the chiller cooled it down by 2 degrees which is better than I thought due to the small size of the device.

    @Paul B If you add some cfl lights & turn your chiller into an ATS, would it not do the same but it would now work as an ATS/chiller combo? Was just wondering as it could also save a little space.

    The lighting is LEDs, I threw out the MH lights. I also have a five foot long algae trough. There is an exhaust fan you can see in this picture that brings humidity outside.
    It is 104 degrees here in New York now and the tank is about 80 degrees (F)
    I don't need a chiller, this is just an experiment. This thing used to by my wet dry filter many years ago. I sliced it to make it fit in the space and re designed it into a chiller.

    Today I had to turn off the chiller as it made the water too cold, For 40 years I used to have to put ice in the tank in the summer.
