Recirculating Biopellet reactor help

[fessoclown]

I have a GEO UMC 420 that I would like to run Biopellets in. Here's a picture of the reactor, it is fed from the bottom:

is there a thread or a parts list somewhere for adding a recirc mod to a reactor?
Anyone done this that can explain to me what I would need to do it.

You can run biopellets in it without doing anything.

look at the other biopellet reactors in the market like reefoctopus, aqualund, or reefdynamics.
you will need a 1 1/8" hole saw to fit a second uniseal (1/2") uniseal near the top of the reactor.
get a pump that will have female/male 1/2" fittings like sicce or quiet one in the 200-400 gph.
all of the reactor designs have two unions, one ball valve, and (2 to 3) 90 degree elbow. all of course 1/2" which includes the piping, one t and two john guest fittings (one for input and one for output). the output john guest fitting should have a valve to regulate flow coming out of reactor.
