Hello my fish Friends. Im in process of setting up my 6 tank in the basement. So far everything is running on Coop sponge filter and each tank have heater but i want to switch to “central heater”. During winter times its gets really cold down there and i will like to heat up whole room. Its medium to small size room and im looking for recommendations for best way to heat it up. I have easy access to gas pipes/220v and central heat ducks. Thanks in advance !
