I'm about to rebed my carbon filter with Centaur carbon, and have an extra 10x54 tank to use to get it set up, soaked, etc. I obviously can't use the existing bottom basket (if any) and pipe from the controller (a 2510, I think). I'd have to disassemble the running tank to find out how it was set up, and would rather not do that. What sort of bottom basket should I use, and once that's in, how long do I cut off the pipe to mate up with the controller -- even with the top of the tank?
