Think I'm going with the BRS model. Good reviews too, as does the Via Aqua. The BRS can stand up to backflushing and has comments about being very sound. Mine is gonna be an external (to the sump) install. Right at the cabinet door opening. 30" accros/horizontal and 18" down into the sump is where the pump goes.
With a MJ900, that should give me about 106 gph
thru the reactor. A 1200 gets about 182 gph
. An MJ600 gets 86gph - all factored with the head loss.
I'm leaning to the MJ900/106gph. Opinion??
The BRS clearly has barbed fittings so I can run flex hose and place the pump and output where I need them.
