3 Fans Aquarium Chiller Fish Tank Fan Aquarium Cooling Fan, 1 Yr Warranty

This fan works only on small fish tanks. Didn't work on my 20 gallon obviously was too big🙄. It saved my bettas in a 5 gallon tank during the heatwave.

Ayuda bastante para la temperatura de los peces, es de muy buena calidad y no hace mucho ruido.

My tank that I'm currently cycling was hitting 90° where I live in Jamaica. I originally wanted a betta fish to inhabit my 5 gallon fish tank, but I knew it would not survive in such high temperature. I started searching and searching for something within my budget (since i had more to get for my fish tank) and came across this. I bought the dual fan version since i wanted the most i could get out of it. I would've gotten the triple version but i would not have the space for it. My hopes were hanging by a thread but this thing surprised me. The first night i tested it out, the temperature went from 90.5° to 81.5°. It was just enough to keep the water cool and I am grateful. During the days when it's extremely hot (summer in Jamaica), it obviously gets a bit warmer, but it's on the bridge between 82° and a little over 83°. I think my future betta will be able to live with the slight higher temperature (fingers crossed). I just know it's definitely an improvement compared to 90° up. Btw, it's a fan so you will hear it. I use mine on the higher speed, yet it's not too loud but it's not silent. I use a fan for myself regularly so the sound of this fan is overpowered which means it doesn't bother me. For other people who are sensitive to sound though, it's up to you if you can put up with it for the better of you aquatic pets.

Despite being advertised as quiet, it's really noisy, no way you would want this in your lounge room or bedroom. See the video. I wish I hadn't waited until weather warmed up and return window had closed before using. Not fit for purpose, I would never inflict this volume of noise on anything in aquarium.

Buena calidad, llego en tiempo y funcionan muy bien
