Any user of this mini chiller tried chilling a 2' tank? Just curious what it can perform to.

Have you tried cooling to a lower temperature?

Read up on TEM so that you know how it works and its limitation. I'm using a similar one for 36cm x 22x26 tank. Personally i feel its just a good alternative to fan as it doesn't evaporate water from the tank and temperature is better maintained so this all leads to a more stable environment especially for such a small tank.
TEM chiller still depend a lot on ambient temperature so if your room's exchange of air is very good then the chiller will be operating more optimally. 26 degrees i feel is the best compromise. Lower temperature is possible, just how long it takes to reach and the amount of hot air it generates to your surroundings
hi guys
i found out that if your TEM exhaust fan is place near the window. not directly under the sun.
it is much more efficient as the hot air is driven out of the window and not into your house. it can make a 1-2 degrees difference. try it.
do not put your tem enclosed inside your bottom cabinet.
btw with tem a stable 24degrees is consider a achivement laio man.
Been using a mini chiller aka thermoelectric chiller for 1 month. Set the temp to 25 and my tank temp normally stays within 25.2 - 25.8 even in the hot afternoon. Have not check my electric bills yet. My tank size is 1.5 ft which can contain up to 17L (Gex Slim 450). It will take some time (1-2days) for the temperature to drop on the initial start.
hi bro igtenos,
do you have condensation problems at 25c?
Nope. I don't.Originally Posted by johnchor
Hi Guys,
I just got one of these chillers and do you guys use the F0 and F1 functions? I can't read Chinese so it's a bit tough to understand the instructions. I know F0 means the temperature degrees fluctuations before the chiller kicks in and brings down the temperature back down to 25 Degrees. But what is F1? Is it deviations from the actual temperature?
I have condensation when the temperature is set to 24, so I was thinking to set it at 24.5 but there is no 0.5 increments. Does the F1 function help to do that?
F1 is for zeroing.
E.g. if you got another thermometer, you can calibrate the temperature sensor on this mini chiller to be the same temperature.
Oh got it. Thanks
I tried this chiller on my 30L tank yesterday evening. Set the temp to 25c and it dropped from 30c to 25c in about 7 hours last night.
But today when i reached home, it struggled to reach 26c. Granted, today was quite hot, I measured the water on another container was 32c.
Another issue is since the chiller is hooked up to the Eheim 2213 output, I have to use pipe reducer from 12mm to 9mm. The output flow is now almost halved and the filter is noisy, scared will kill my Eheim motor

Did the same as you. My chiller has been running for 1 month plus. Also used the reducer and dont seems like there are any problems as of now to my eheim aquacompact 40. Filter don't really have any noise.
Aquacompact 40 the pump is inside the tank and normally the canister sits beside the tank.
My canister is way below my tank so the motor has to push the water up, normally this is not an issue at all, the motor is always silent & flow is very strong.
But after I hooked up with my chiller, as you can see the white pipes connecting the chiller, the motor is now struggling. I guess I will get another pump just for the chiller.

It wouldn't have crossed my mind that restricting flow rate on the outlet side will cause such issues. I was actually considering getting a mini chiller and connecting it to a 2215 for probably a 45x30x30 tank.

Your mileage may vary depending on the placement of chiller & canister as well as the length of the hose. Plus, your 2215 is stronger so you might have better performance.
But on the other hand, unlike compressor chiller, this TEM chiller performs better on slower flow since water will spend longer time inside the chiller. Alvin from Aquarist Chamber recommended around 100L/H flow. The Eheim canister is way above that.
100L/Hr flow rate seems to point to the smallest external power head available in the market. Is these anyway to 'shrimp proof' such a power head though?

I guess you could just cover the intake tube with a sponge guard.
Alternatively, you could also use a small submersible pump filter to power the mini chiller, something like this:
They are basically just power heads with a sponge filter cartridge attached to their intakes, those will be shrimp proof + you get some additional filtration too.
Your chiller seems to be different from the model that is sold locally by Aquarist Chamber. Are the specifications the same?
For the locally available model, seems that an Eheim 2211 is a perfect choice with the 9/12 hose size. 300L/Hr flow rate can be negated by packing in more medias and probably a tap to reduce outflow if needed.
