Reactors connection

[kilo]

Guys,

Planning to run two reactors on my setup. One for nitrate and the other for phosphate. Can connect the two reactors in series?

It goes like this: pump -->reactor 1 inlet --> reactor 1 outlet --> reactor 2 inlet --reactor 2 outlet --> back to sump

Reactor 1 for phosphate and reactor 2 for nitrate.

Pls advice

Yes, it is possible but you might need a strong pump and also a valve to control the flow In/Out in order to have both reactor media fluidize.

Possible but not what I would recommend. Better to T off the pump supply to each reactor.

I assume Nitrate reactor refers to biopellet.  Generally, these need much higher flow than Phosphate reactors (eg Rowa).

The suggestions above makes sense. 

Another option is to connect in series but with a T off & valve in between the 2 reactors. The valve allows some water to return back to tank & a lower flow to the 2nd reactor.

Pump -> Nitrate reactor -> T joint/valve (to output some flow to sump) --> Phosphate reactor -> Output to sump

That was fast replies. Thanks alot for your suggestion. T joint between reactor sounds like a good idea.

U can make a manifold. But u need a stronger pump.
