I was wondering what some alternative ways are to cooling axolotl water down. I know you can buy chillers but those are all around expensive and ive heard theyre also noisy. I live in Georgia so the summers here are incredibly hot. I do plan on having a window unit on but for the mean time I was wondering what are some other ways. I was debating on trying the water bottle method. Some people say it works and others dont. I also have a 20G aquarium.
