Aquarium Chiller, Fish Tank Cooling Fan System for Salt Fresh Water, 2 Variable Speed, Wide Angle Adjustable (2-Fan)

We just got our axolotl over the winter so keeping it at a safe temperature for him hadn't been a problem. Over the last week or so here in Oklahoma, temperatures soared into the 100's and our axolotl is kept upstairs, so when the temperature of the water in his tank started creeping into the 70's I started doing my research. I found this and after reading all of the helpful reviews, especially for axolotls I didn't hesitate to try it, considering the price of a tank cooler was not something I wanted to have to purchase, but certainly would have if this didn't work. He's a part of the family. I'm so glad I made this purchase. It is literally a life saver considering my research informed the that the ideal temperature for them is between 60°-64° and anything above 70° becomes problematic, even deadly. I received the tank yesterday after work, about 4:00 and the temperature on the tank was approaching 72° (first picture). I immediately took it out of the box, plugged it in, and like other reviews stated, it didn't fit over the top of the tank, but for now it's being held up by the glass lid I had over the tank (second picture), works fine, but I will try velcroing it, like another review stated they did so that my son (he's not a child, he's 16) doesn't accidently knock it into the water when feeding him. By 6:00, in the heat of the day and when the upstairs A/C is only able to cool the upstairs to 75° and with the fans on high, the tank had already cooled down to 68° (3rd picture)!! 4° in just two hours! I was very happy and so was he. He went right up to the fans and stayed there for a bit, almost like a human cooling themselves in a fan. I think he liked the current it gave off, but it was cute. The fans on high are a little loud, I mean, it sounds about like a little desk fan you would have on high. I checked again on his temperature when I woke up this morning and it had cooled his tank below 66°! That's as low as my thermometer reads so if it's lower than 66° or higher than 84° the thermometer strip is just solid black, so given that it was below 66° I felt like it would be okay to turn the fans to low. After coming home from work today, again in the heat of the day, with the fans on low he's setting at a cool 66° (4th picture). Couldn't be happier with my purchase!

It's been working great

This Chiller does work as expected to lower the temperature of the water for a safe aquarium. Very happy with the purchase. Fantastic aquarium chiller

The media could not be loaded. I originally bought this because the reviews seemed good and I just needed to cool my tank down by about 3°. I got the fan in Tuesday evening and immediately regretted buying it. First. The package itself was beat up but also it had clearly been opened and used. When I pulled the fan out it was incredibly dirty, not just dusty but It had looked like it had sat on the back of someone else's aquarium for a very long time and built up gunk. I decided to still see if it worked and when I went to plug it in the side that the AC adapter plugs into literally fell off. I could see that it had been broken before and was just sort of pushed back on. I did plug it in and turned it on and only two of the three fans worked. The third fan made an extremely terrifying rattling noise. The packaging inside of the box itself was also damaged and everything had looked like it had been clearly opened and used before. The product itself looks old, even if it was just old technology, it still looked like it had wear and tear.I would absolutely not recommend this to anyone. I went back and looked through some of the bad reviews and noticed that other people have received broken, dirty, and used fans as well. Probably this same one. Not really worth the gamble.

I've only received this fan today and so far so good. I got the single fan and did a temp test on a 15 gallon tank. It dropped the temp by about 1 degree in about 10 minutes on the low setting. Given more time, I'm sure it will perform well to drop the temp of the water even more. I'm using it to keep my temps to around only 78° F and so far, I'm certain it will do just fine for my needs. The fan is not quiet by any means, but I will only really use it when I have to during the warmer days.While yes this bracket is for rimless tanks, I did install it on a framed Aqueon rimmed tank and it does fit over the thicker edge of the frame. The front part of the bracket rests on the lip of the rim where a glass top sits. It fits sung enough that I'm 100% confident it will not fall off on it's own. The tightening screw of course can't really be used as normal this way, however when installed, the threads sit over the top edge of the rim and I can see in the slim chance the fan does get bumped and tilted, the screw will act like a brace keeping the fan even more secure from that happening.All in all, I'm happy with the purchase. Time will tell how long the unit actually lasts for.
