    hi all,
    i'm considering buying a chiller for my planted tank(about 100 litre). can anyone share their experience on the up & down side of owning one? will the heat generated by the chiller be too much to bear in an enclosed room? how about the noise level? the cost of electricity per month?
    thanks for any advice coming this way

    think the answers to your question will be similar to running a small bar fridge.

    I am using a Teco 680 chiller for my 4 feet. It is rated at half horse power. When the chiller comes on, you can hear an audible sound akin to a small aircon compressor running. There is also some heat generated...hence the chiller should be kept well ventilated. I put my chiller directly below my tank so the heated air goes up to the underside of my tank...substrate heating!!!

    The advice I was given is to go for a chiller that is MORE than sufficiently rated for your 100lt. To give you an idea, the Teco 680, I believe, is rated for up to 1200lt at 25 degrees and my tank contains at most 250lt. That way, the chiller comes on for not more than 20 mins to cool down from 27 degrees to 25 degrees on a hot afternoon with full aquarium lights on.

    Only issue is the cost of a more powerful chiller. But in the long run, I believe you will see a lighter electricity bill...compared to an under-rated chiller turning on for most part of the day and into the night. Heard of someone's chiller being on all the time.

    Hope this helps.

    Beagle,

    Your 680 took just 20 mins to cool a 4ft from 27 to 25 degrees! What pump or filter is connected to your chiller? PL, FL or MH lighting? How often does it crank in a day?

    Mine took almost 2 hours to bring my 5ft temperature from 28 to 26 degrees. But I am using a substrate heater that is underrated and the chiller is connected to an ecco 2233. The difference in timing is so significant although my tank is a little bigger and has subtrate heating.

    Am using an Eheim 2026. Using FL lighting (38 watts X 2). Tank size - 120cm by 45 cm by 50cm. I think my chiller has a lot less to cool than your 5 feet.

    Anyhow, just timed the last time it cranked up to cool from 27 to 25 degrees -about 24 minutes.

    Dun think you can prevent the condensation. May I know what temperature did you set at?

    Wow...your fishes must be freezing inside []. You can set at 26 to prevent condensation. No good for wooden cabinet if you are using one. Anyway, is the reading from your chiller or thermometer? Those normal thermometer might not show a accurate reading. Your fishes might be experiencing temperature below 25 degrees. Best to get or borrow a digital one to test. Lastly, is your chiller(if Teco) calibrated?
