Aquarium Chiller Fish Tank Cooling Fan System for Salt Fresh Water 2 Variable Speed Aquarium Black Aquarium Cooler Fish Tank Cooler Clip on Chiller (4 Fans)

These are loud, I wouldn’t keep them in a bedroom, but they do keep my 20g tank cooler than what it was. I was sitting at around 70 degrees, but now it’ll sit in the mid-low 60s at the low setting and high 50s-low 60s at the high setting. Be prepared for the water to evaporate faster of course. Was a good investment for my Axolotl verses getting an expensive water chiller! Worth the money for sure.

First, it’s very loud. Even on the low setting it is disturbing and annoying. 2nd the chord is not long at all. 3rd and most importantly, it is JUNK! I left it running while I went to work so that my axolotl would be safe and I came home to it not running. I plugged it into multiple outlets and it doesn’t turn on at all. It also doesn’t fit most tanks at all. Don’t be duped

The media could not be loaded.  I initially bought this to cool a 20gallon long tank because I didn’t realize that I would probably need a real chiller.I don’t know how effective or consistent it would be cooling my 20 gallon. I live in Texas so I haven’t tried it during summer months, but currently the ambient temperature in my house is around 76°.I made the mistake of impulse buying an axolotl even though I have wanted to for a long time. Previously I cycled a tank for one but never had any luck finding an axolotl at my local fish stores, so I turned it into a betta tank. In my impulsivity, I did not have a tank cycled and need to tub my axie until the tank is ready. For the first 2 days of tubbing I was using ice packs to keep the water cool, but the temp was inconsistent and it was a lot of work. When the cooling fan arrived I was able to set it up next to my tubs to keep the water around 67°. For reference, my tubs are equal to about 8.64 quarts of water each. The water from my faucet was 76° and within 40 min my water reached 67.6°. Pics will show the setup for cooling and vid shows how to maintain the cooling. When initially cooling I had the fan set to the higher air flow and for maintaining temp I had it set at the lower setting with fans indirectly blowing as to not disturb the water too much.I dont think it will lower the temp in my tank enough or be able to keep it consistently cooled. But I’m glad I bought it so that I can use it for tubbing until my tank is cycled or if in the future for some unforeseen circumstance I need to tub my axie again, I will have it. Or I can also use it to supplement my chiller in the summer months.

I wish these would have worked for my tank. I have a 40 gallon TopFin breeder tank and due to the top of the tank having a black rim that could (in theory) hold a lid this chiller can not attach to the top of the tank. The clips on the chiller are not wide enough to handle the width of the top of my tank. If you have a different brand tank or better yet a rimless tank this should be able to attach without issue.Side note, I have yet to find an aquarium lid that will fit the TopFin 40 gallon breeder tank.

Used this to drop the temp in my axolotl tank worked great for a 40 gallon long! I did use 2 but it dropped my temperature down a good 8 degrees

It was great at first when I put it on my tank, but then a couple days later I came home from work to see it not on, I checked to make sure the switch didn’t get flipped or in case if the power flashed but it just wouldn’t turn back on again. Also seemed like very cheap plastic and it was really hard to get on my tank. I was really excited about this product because I have 10 fish tanks all ranging between 10 gallons and 55 gallons but it was really disappointing that it stopped working so quickly.

I started using this product Monday, April 14, 2024, it has been on to keep my Axolotl tank cool. I walked into my room to check on my Axolotl about 25 to 30 minutes ago and the fan was plugged in and set to the on position but the fans were not running. I didn’t see one of the reviews until I started using the fan that somebody had the same issue. I was hoping that it wasn’t the case but unfortunately it did break.

One thing I don't like is the two middle fans are easy to move up and down but the two on the sides are harder but it really isn't a big deal still perfectly works

Doesn't do much of anything for a fan that costs as much as it does. Don't waste your time or money.

Having trouble finding a 12v power supply that works.
