Cooling fan for 20-gallon high tank

Fans can help, but they're not a long-term fix if your room's always hot. Might wanna look into a chiller if it's a recurring issue. What's your budget like?

Agreed. Unless you're keeping super temp-sensitive species, a fan should suffice. Just remember to monitor the temp daily until you find the right balance. What's your stocking like, willow95?
