    Ok, so one big complex reef tank just wasn't enough for me LOL - so my son and I started a Nano + sump for local cold water marines. All is going well except for temperature which we cant get under 20 deg celcius. We jimmied a bar fridge I had lying around and pass water through a thin flexibl hose to help matters.

    A pic for now

    Nah the bar fridge doesnt work, so a warning to DIY guys out there, dont try it you will just waste a perfectly good bar fridge. The best I get is 20 deg celcius which is kinda okay but I susepct that the livestock wont like extended periods at that temperature. Im researching the stuff they use to liquid cool computer CPU's with. Its only about 150l of water so something other than a proper R100000000 chiller must be possible?

    Sams aquariums (a sponsor) is selling dolphin chillers for about R1300. I looked at it but it just looks like fans blowing over heat sinks with water passng through. I gave it a miss.

    The next plan is to find some miricale way of spliting my existing mega chiller that runs my main reef DT to somehow provide chilling to both tanks seperatly, much like central airconditioning in a house with multiple split units running of one outside compressor unit.

    The mind boggles but at least its a challenge:razz:

    LOL! Cool Ashraf! Hope that this works for you! ;) Perhaps you should INSULATE the clear-tubing.... otherwise the room temp warms the water up too much again... also how you getting the water through the clear-tubing? A pump? What size pump?

    I'm teeing of from the main return 2000lph lifetech pump in he sump. The water is kinda dripping out of the flexible hose at the affluent end so its definatly slow enough to get chilled.

    Ambient temperature in another qt tank I have is about 25 degrees without the heater on and the local nano is now at 20.5 degrees so its working, just not enough

    amalick: if you are struggling so much with temps now, whats it going to be like in full blown summer? Sorry mate but my opinion is if you're wanting to run a cold water tank, get a proper chiller.

    Very cool thread amalick! I'm watching closely. Been thinking of doing this for quite some time.

    Hi amalick, please note im not saying everybody should run out buy a fridge & try this...but it does work (just not teally worth the effort & running costs) what i guess the reason for yours not working as well as you thought is twofold.

    not enouch coiled tubing (doesnt seem a lot in the pic but i might be wrong)...you really need a LOT

    as everybody said insulate tour tubing...you can get a silver "space blanket" type sheeting from builders (sorry dont know what its called), wrap around your tbes etc

    at least you can put a few :peroni: in there as well and always have some handy aright by the tank:thumbup:

    Hey Ashraf! What happened to this tank of yours? I agree with what Frans said. I actually did go, and spend R1452 on a 2nd hand chiller..... I am running my cold water / temperate water tank, at 19 degrees celsius at the moment.... my chiller does not come on much.... let's see what summer holds ;)
