You may run into flow issues if you try to link them inline with one pump :scratch: You'd have to split the outflow from the pump to each Reactor. Depending on how many Reactors you're talking about, it may be simpler (less wattage) to have a dedicated pump for each. I'm using a throttled down MJ900 until I get something with less GPH.
Ok, on my single unit (which is how it is now) I am using an MJ400. I will continue to use the NJ400 and put a "t" or "y" adapter and split the flow instead of linking them,
It's best to parallel them, but you can still run it in series. It just depends on the flow required. i would think the higher flow media would go first and then the slower flow media last. But if you need good flow through both i recommend just t'eeing off the pump.
Phosban media in Phosban reactors require very little flow to be effective, probably around 80 gph or less. The media should only tumble slightly on the surface.
With such little flow, I actually tee off a MJ-1200 3 ways to run a Phosban reactor, to feed my calcium reactor and to also run a MRC fluidized reactor with about 1 litre of Hydro Carbon.
Carbon used in reactors should not tumble as the carbon will break down.
