Thanks. It’s been an fun ride. I am in the process of cleaning up an old sump (removing baffles and cleaning up silicone) to use for QT. But I really can’t complete a QT tank because I don’t have completely cycled rock to put in it. I picked up a large one of those sponge bubble filters and put it in one of my sumps so it starts building up a bio load. Also picking up some bricks (got that from Paul) to use a bio holders for qt. That way if I have to treat a fish with medications I’ll just toss it out and use a new one.
