Ca reactor feed question

[Delphinus]

As Kari mentioned I did pop a reactor having fed it off my sump return. Came home to find an incredible mess and an empty sump.

My mistake was making the flow adjuster valve on the output of the reactor. I highly recommend putting the flow adjuster valve on the INPUT side of the reactor.

Even if the reactor can handle the pressure, another point to consider is that a reactor under pressure will want to leak more than a reactor that isn't under pressure.

Other than that, really, anything that works, works .. I've seen people use gravity feeds, little powerheads (that's what I use nowadays .. an itty bitty maxijet or minijet something-or-other), sometimes even the recirc pump can have enough suction and discharge to draw water in from the tank and push it back. Like Pescador mentioned, you don't need pressure to run the reactor, just a slow flow and a way to fine-tune the flow if need be. 60ml/min works plenty fine for me with my current bioload and tank size.
