Pump size for TLF reactors with GAC and NP biopellets?

[cwatkins]

A half full TLF reactor with pellets BARELY tumbles correctly with a wide open MJ 1200. A 600 would work for a GAC only reactor.

If your return pump is large enough you should look at teeing off of it to run your reactors. I run a Vertex UF15 with bio-pellets, and a BRS reactor for carbon teed off the return line from the Barracuda. No more piddling around with MJ's clogging up etc.
