So, I am adding a third 10 gallon tank to my basement. They are all invert only tanks. I'd like to run the three of them off of one DIY filter. I've been scouring the threads and not finding what I'm looking for. Any recommendations? I'd prefer to NOT drill the tanks. There are currently 3 tanks, but it'd be nice to leave room for a couple more down the line. Bucket type filter? Rubbermaid (tote) type filter? I have NO idea!
