    Hi all, fish noobie here! :)

    I have a question if someone doesn't mind answering. I am trying to heat up my 20g with an added 10g sump and I want to put the heater and filter on the sump. Do I use a heater wattage appropriated for 20g or 10g?

    I'd go for wattage for 20-30 gallons as the tank is technically 30g (the fish can only access the 20g).

    I'm pretty sure that's correct but hopefully someone else could confirm it .

    Go with Ethan's advice

    Ah ok, didn't see it as a 30g total as I was unsure how evenly spread the heat would be between tank and sump. Was afraid sump would get too hot and cook the fish :/ Thanks a lot!

    The heater will distribute the heat evenly amongst the sump and tank as long as the sump is always on.
