Hi Everyone, Can someone give me some suggestions or advice on how to keep the temp in my 10 gallon tanks as stable as possible? During the colder months this wasn't a problem but now that it's hot out it's become such a task to try to get the tanks to not fluctuate in temp. I have cobalt neo-therm 50w in the tanks set at 78F but because of the heat and the room temp the tanks are at 80F. So now my goal has been trying to keep it at 80F. I thought about getting chillers but with 3 tanks it gets really pricey. When I'm here during the day I run the AC to try to keep the room temp down but I can't just leave it on 24/7. I just would like some peace of mind so if anybody has any ideas I would greatly appreciate it.
