This wiki has been updated 3 times since it was first published in January of 2019. Water that's too warm is a common problem for fish keepers, caused by living in modern climate-controlled homes or hotter environments. Whatever the source, one of these aquarium chillers is the solution, as they lower the temperature to ensure that everything goes swimmingly for your finned friends. Note that many don't come with pumps, so plan your purchase accordingly. When users buy our independently chosen editorial picks, we may earn commissions to help fund the Wiki.

Editor's Notes

January 24, 2019:

Selected the Hamilton Technology Aqua Euro Max and the JBJ Arctica as top choices for those with moderate to heavy-duty cooling needs; they certainly aren't cheap, but they offer exceptional usability and work well in a wide range of setups. Omitted many low-quality fan models, as they are not known to cool much at all, with the exception of the yubo iPettie. It also only cools by a few degrees, but its low price might make it appropriate for those who are okay with this small temperature drop.
