    :lol::lol: I have to laugh dude...you're in the same tank as me!!!! I had the same thread as you 2 days ago. My tank was at 30C and summer hasnt even kicked in yet! Try some fans for starters blowing directly onto as much of the tank water surface as possible.i was told to do the same and my temp dropped 2degrees in an hour or five. Then when you can afford a chiller get a hold of SIMS.

    goodisor is right. PC fans saved my tank from 30 degrees, it now sits comfortablt at 25-26. the seceret however is placement.

    1 - more fans the better. minimum 2 i say

    2 - if u have a closed canopy try getting a pc fan to blow air in on the one side and another to suck(hot air) out on the other side. where as open top, just one fan accross the surface.

    3 - next fan should be placed on the sump, especially if u have a cupboard, it gets hot in there. try drilling a hole in the cupboard(preferably) and get a fan blowing cool air in to the sump area.

    4- hole dimensions 80mm for your general R30 cooler fan and 50mm usually for a CPU fan

    5 - if u cant drill your cupboards, leave the doors slightly open and stick a fan in there somewhere to create air flow!

    Worked for me and its a much cheaper alternative to a chiller. oh and its working fine and its 34 degrees outside today...

    total cost( fans = R30 80mm and R40 120mm) and (a DC transformer R70)

    hope it helps bud

    Unless you are in the industry don't waste your time with a DIY chiller, seems they never work too well.

    scruffels, if your tank is smallish perhaps consider a Peltier effect chiller. I think Boyu makes a few sizes. The cost is under R1000, I think.

    Otherwise fans work really well. The regular PC fans packed up on me pretty quickly, so if I were you I'd try find a proper alternating current cooler fan. Hardware stores often have cheapish extractor fans for bathrooms.

    Hi guys - I had a brainwave the other evening..... Why not get/use a small electric (12 volt) motor-car radiator fan? There's a company here somewhere's that sells them for like between R120 and R180.... these will be able to cool the water one HECK of a shot!
    BUT - I do think they might be slightly noisy though...

    try your local aircon wholesalers.They sell all sorts of aircon parts including some really decent fans of all sizes.Ive never bought one but ive seen them there and they look neat.Ive got a single fan blowing directly on my sump..today the temp was 34 degrees and my tank maintained 27.5. They really work well. [​IMG]
