    Hey Guys just thought i would share this with all of you...


    I resently started my system and started doing some reasearch on how to cool down your water without using chiller... Dont relly have the money to buy a chiller so started doing some more reasearch...

    I have a system now that is controlled with a diy temp controller that controls my heaters and my fans.. I have 4 x 220 v fans and 2 x 300w heaters. My temp is always at 26.deg

    The system works like this, the temp meter hangs in the water measuring the water temp like most digital temp controllers, if the water temp goes below 25.5 the heaters switch on and if the temp goes higher than 26.5 deg the fans go on...and the heaters swith off.

    Use Pc fan to blow either over the display tank or sump, that dropped my temp by 2. Put PC fan to work while display tank lights are on.
    Use a scrubber. That drops it another 4.

    Now my tank is to cold, and I had to switched the fan off.

    For really effective CHEAP cooling, put the pc fan to blow accross your scrubber.

    Only negative, you have to top-up a lot more per day as it is the evaporation that cools the tank.

    Cost of Chiller vs Cost of RO water...

    You can get a dedicated aquarium fan for a lot cheaper than that.

    His system is for fans, heaters & temp probe to control heating & cooling not just cooling

    Cool! Just remember, if the ambient temperature is high, you won't be able to decrease the temperature that much --- before I bought my chiller, my temperature would go as high as 33 degrees in summer! Yeah, Windhoek is probably a bit hotter than anywhere else ;) G'luck! T

    Hi Guy's.
    Have 2 220V 120mm Fans blowing at suspended MH's and it has increased cooling significantly. However, in the somewhat overheated Cape at the moment, not adequate. will be adding 2 more. Tank uses about 25 L RO per day.

    The other adjustment made was to move band of operating temp up from the 26 degree mark to 28. This ensures stability given the excess temps currently being expierienced. Now temp does not exceed the dreaded 30 degree mark.

    Computer fans are 12V and not 110V.

    the funniest thing i've heard of , it's a guy , who piercced the wall behind is tank to go to the kitchen , where he pierced is fridge , ran a pipe from the tank to the freezer of the fridge , and a the water circulating to the freezer and back to the tank .
    i don't know , if it worked , but for sure my wife wouldn't appreciate :)

    Probably Chicka, but that would also be the issue with a normal chiller....buy new one

    This does work, BUT very expensive to run and difficult to maintain temprature 100 %
