Zoo Med Aqua Cool Aquarium Cooling Fan

This item works well with my aquarium, I have a 20 gallon saltwater aquarium. I just set up my aquarium about 6 weeks ago and the temperature has been 2-4 degrees too high. When I placed the aquarium cooling fan on the back it reduced the temperature 2-3 degrees. This fan works as a cheaper alternative to a chiller which can cost $200-$400 unless a dramatic decrease in temperature is needed. The only complaint is after a week of daily use when turning it on in the morning it tends to make a loud buzzing sound. If you tap the back of the unit with your hand once or twice it will stop.

Product works great, cheaper than buying a chiller system for my 34 gallon Red Sea Max 130g tank. I must run this fan during the summer even with the A/C on because the tank gets so hot. It generally cools my tank down by 3-4 degrees. Definitely worth the money. I'm very happy with this purchase and I have had no problems with this product. Definitely would recommend this product for those you can't afford or do not have room for a chiller system.

The water temperature was definitely controlled, but after less than three months, the internal rattling sounds became unbearable. I will replace with a different type of fan.

I have a nano reef tank and this is the first summer it was set up. The water temp was going over 82+F even when the house temp was 75F

I bought this and it works great. It is quiet and cools the tank to mid to low 70's even when house temp is now 79F. I have it on a multiple setting timer and it turns on and off throughout the day. This way I can keep the temp consistently around 75F

Awesome product and great price compared to a chiller!

This is a great buy. I bought this for my saltwater 20g set up to bring the temp down after installing a power head which raised the temp several degrees. Within the first hour after installation, this fan brought the temp down a full degree!! Quiet, efficient and cost effective I strongly recommend this fan. This uses evaporative cooling to bring the temp down so be prepared to add water to your tank on a semi regular basis. No complaints about the product, does just as described and I saved over $12 buying this on Amazon vs my LFS. After two 48 hrs this fan brought the temp down a full 5.2 degrees in my tank. My fish seem much more comfortable and I'm not as nervous about stressing them out due to water temp being too high. Now, if only I could get my snowflake eel to leave my blenny alone. :) super fast shipping too would do business again with this seller!!
