    bought a mini samsung fridge at $20.00 from ebay. just finish drilling the hole and pipe fitting.
    running on an empty (just fill with water only) 4ftx1.5ftx1.5ft empty tank using a jebo power head to circulate the water form the tank to the mini fridge (don't know the waterflow rate)
    will update tomorrow morning of the outcome.
    any brother interested on my diy project are most welcome for discussion
    or joint project over at my place.

    Bro,

    You have a very smart idea! Is the electricity consumption the same as normal chiller?

    Hi.bro.Blackhawk / Spid

    Just check the tank after running for 24 hours.The water temperature was down to slightly below 25C , was 30C yesterday. My current planted tank water temperature was running at 26C.should not be a problem if i shift the diy chiller to replace my current Hailea chiller.Sorry don't know how to insert picture here,can someone/senior kindly guide me on this issue)

    I was poorer by a few ten dollars when using a hailea chiller every month
    will be able to save alot as the mini fridge are running at low cost,

    mini fridge 80watts x 24hrs x 30days= 57,600watts divide by 1000watts =57.6kilowatt x $0.25 =SGD $14.40 per month.(correct me if i am wrong)
    Quite a big saving.
    Will update all bro again tomorrow night and try to find a way to upload the picture.
    Thank

    hihi all, am back. check on the tank temperature it reach 24C.
    as promise will try to upload some picture to share with all bro here.

    pic ;tank water temperature taken last night around 2200hrs slightly below 25C

    pic.1; mini fridge bought from ebay and my future 4x1.5x1.5 tank

    pic.2 ; inlet and outlet water flow pipe. i use a 1/2" holesaw to drill it, was blessed when drilling the 2 holes, manage to advoid the refrigerate pipe,wiring and heater which cannot be seen from the external housing of the fridge.as this is only an experiment i did not actually secure the pipe with PVC glue just a few round of wire tape does the job.

    pic.3 ; secret behind close door. i manage to reach to my expected water temperature, might be due to the following reason ( seen many post on diy chiller by other bros but failed IMHO maybe they are using the wrong method)
    1; i use an aluminum tray instead of a plastic tuberware ( aluminum tranfer heat faster then plastic)
    2; i use the normal water hose instead of the Ehiem hose,(normal water hose are thinner compare to Ehiem hose, is only half the thickness of the Ehiem hose)
    3; beside water i add ice cubes to maintain a lower cooling temperature in the tray.
    4; try not to open the fridge door to often to maintain the cooling temperature inside.
    just a few line here, hope bros here can understand my procedure of the diy chiller.
    will continue to monitor for the next few days and transfer all my plants from this 3feet tank to the new 4feet tank.

    anyway million thanks to bros who are keeping track of my project.
    hopefully the temperature will drop to 23C tomorrow morning.
    going down to sim lim tomorrow to get some led light for another project for light off at night >>> moonlighting any bro interested in this diy moonlight project are welcome to join me.

    thank and regard

    IMHO, if you could replace the hose from rubber to copper is the best.


    cheers!

    hi windcharm
    for a diy chiller i don't think i am able to get the temperature of 23c and also depend on the light i use.Every morning the water temperature read at 24.5c all the way to 4.00pm when my light are on ( 4x39watts T5HO) and gradually increase to 26.5 at night with the all the light on (10x39watts T5HO) my tank light are off at 2359hrs.
    anyway the water temperature when using the chiller was maintain at 26c to 27c which was very comfortable for myself and the environment inside the tank.to be able to get this reading for the diy chiller was a great achivement to me spending only a little sum of money and saving alot on monthly electrical bill.
