79 Gal Aquarium Chiller, 1/3 HP Fish Tank Water Chiller with Quiet Design Compressor, Refrigeration for Hydroponic System Axolotl Jellyfish Coral Reef 300L, Black

January 18, 2026 Just purchased it and it seems to be working just fine. I love that. It has a way to have a temperature range to turn on the compressor to start the cooling process. I will continue updating over the next few months and years as necessary. Before putting it together, I used both rubber, gaskets one on top and underneath the water outlet connection in addition to using plumbers tape. It’s best not to over tighten being a plastic nut and bolt thread instead have a better seal by using the tape.

This works great for my cold plunge tub. I don't know exactly how many gallons my tub is but it's around 90-125 gal. I would recommend comparing the thermostat of the cooler with a thermometer in the water. I believe my cooler was a few degrees off, but it was easy to adjust. It keeps my tub cooled to 41 but will likely go a few degrees lower. When the thermostat was wrong I accidentally cooled it to 38-39 degrees so it can definitely chill the water pretty low. My ambient garage temp is around 60-70 degrees and it runs intermittently. I haven't noticed any large changes in electrical costs. If you cool it really low it will need to run more frequently but 41 degrees is my preferred temp.

The chiller is working well for me, now that I was able to talk to the company and figure things out. The manual that comes with it is worthless. I suggested they update that, and they are going to be doing some working on it to try and make it better. The main thing with this is that it comes preset with a five degree temp swing. So if you set it to 60°, it will start cooling at 65°. But check your tank temperature with a different thermometer and do the degrees according to how much it is off. Mine the chiller is two degrees off of my tank, so I set the chiller two degrees lower than I actually want so it's the correct temp. In order to change the temperature swing hold down the set key until F1 shows. Push the set key once more. The number five will show. Use the arrows to adjust to how many degrees you want it to kick in at. None of that is in the instructions. There is also an F2 setting that you are supposed to be able to adjust the temp gauge of the chiller to match your aquarium if it's off like mine,but I only managed to get F2 to flash once holding the set key and haven't been able to get back into it so I just know how many degrees off it is and go by that. Overall for the price it's not bad as long as you know the quirks. And find videos on setting up a chiller, the instructions included are worthless. The whole manual is very Chinese English. I will update later if it doesn't last for whatever reason. Company is very helpful in trying to help you though and gave me some money back for all the trouble it's been figuring this out.

I used this aquarium chiller to manufacture a cold tub for my spa clients. The chiller is whisper quiet and easily cools this 60 gallon tub. I change the temperature between 45-55 deg F. We usually keep one tub colder than the other. The chiller works so well the client has requested another set of tubs for a second location. Super easy to hook up and chill the tub in few hours with ease. Highly recommend this unit.

My cold plunge has been not running more than it has been running since I got this earlier in the year. All in all I got 3 weeks of use out of it. Made changes to my setup to stop some leaks and change some fittings, put it back online yesterday, and now the chiller is dead. Unit turns on, but does not cool.

Working well for a DIY cold plunge. Holds at 44F in high heat and incomplete insulation. Would certainly go colder, but I haven’t yet set it there. Pre-filter screen, pump, whole house filter and this chiller. So far, all good.

I've been using this with my ice plunge tub and it works great. I did buy seperate fittings, pipes and things but the actual unit is pretty solid and quiet. I do think you should buy a GFCI extension cord if you use this for safety though. But no real complaints, gets it down to 40 degrees easily with an ambient temperature of 80, we'll see how it does it in the summer.

This was a big investment for us, but I decided to purchase a chiller because we really struggled to maintain our tank temp last summer. (We have axolotls and they like to live at temps lower than 70 degrees.) We've had the chiller for about a month and it really does keep the tank cool. The setup was very easy, although we did purchase some clamps to make sure the hoses can't slip out of the tank. (The supplied hose length was enough to meet our needs, but stuff happens and I don't want a flood in my living room!) Programming took a few minutes, because I had to wrap my head around the instructions, but it wasn't too bad. I like that there is a calibration feature to make sure that chiller and tank temp are *really* the same. I also like that the powerhead and cooling unit are independent, since I know we will eventually blow out the powerhead! We have had 2 instances where the chiller has randomly made a lot of beeps and stopped cooling the water. It was easy to reset the machine and it didn't lose the specs that I programmed, but I definitely do double check the tank temp every time I walk by it so I know as soon as possible if something is wrong!
