Aquarium Chiller, Fish Tank Cooling Fan System for Salt Fresh Water, 2 Variable Speed, Wide Angle Adjustable (1-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!

Pretty great product, bit limited in the ways the fans rotate on their axis but oh well. 2 speeds, neither particularly fast but enough to get the job done.

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

DO NOT BUY. It did not last not even a week. The cable is good bc the light turns on but it just does not work anymore. Really bad quality. Buy another one, not this… really sad.If you want to waste your money well then buy😅.

Worked too good, went from 69 to 59. I have a 40 gallon with 4 fan model

I have been unable to find a decent aquarium fan that is made for a black rimmed Aqueon tank. Some reviewers said this fits on a black rimmed tank if you force it or if you damage your tank by removing some of the black rim. This absolutely does NOT fit on a black rimmed tank. It is made to fit on a half inch rimless tank. I am not going to damage my tank and I am unable to find a good alternative "out of the box", so I ordered a three fan Petzilla from Amazon and two adapters from someone who does 3d printing to make this product work for my tank. My total cost was approx $28 for the fan and $37 for the two adapters plus shipping. That's why I don't feel this Petzilla fan is a good value, because I had to buy 3d printed adapters to make it work for my 55 gallon axolotl tank. Additionally, even on the low setting, the fans are kind of loud. They are louder than my filters. The cord is also a bit short. Not long enough to make a drip loop. I will try to leave an update to my review after I've been using the fan for several months to see if it is long lasting and durable. The previous aquarium fan I had purchased in a different style from a different brand stopped working while laying in a drawer over the winter because it was cheaply made so we'll see how this one holds up. The adapters shown in the picture were purchased from Leafgreen Solutions. Overall I am happy so far with my Petzilla aquarium fan. I wish they would make one specifically for Aqueon black rimmed aquariums because this kind of tank is so popular, widely available, and economically priced.**Update** Stopped working after 11 months of continuous use.Pros:cools my tank down by several degrees Fahrenheithigh and low setting and off switchadjustable angle of the fans3 fan heads for larger tank sizeblack color matches my tank trim and filtersCons:louder than I'd like - way too louddoes not fit on typical black rimmed tank without adapter - only fits on rimless tankscord too shortconcerns about long term durability - only worked for 11 months and then died.

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.
