    Setting up a 20g Long with 4 chambers. The dividers have holes, but not as much as I'd like. I am putting a sponge filter in each chamber.
    My question: Would a 15w preset pad heater in each chamber work? I don't feel like there will be enough flow between chambers for a single heater or ever a heater on each end. My house maintains (68)72-74 year round.

    I think you'd be surprised how much flow there is, especially if you have 4 filters. I feel like 2 heaters on each end would do just fine. It is kind of up to you, but 4 would be expensive it seems.
