Mrc cr-4 reactor feed pump question

[basscyn]

I've had this baby for 6 months. I think its time I hooked it up
(ok...Ive been busy. Ready to dedicate some time to the tank again.</em>:yes

This is an MRC CR4 Dual reactor. I have everything I need but the feed pump.

I DO know that I want a dedicated pump rather that gravity feed or tee off my existing return pump. I think the MRC site recomends a Mag 2???
That seems too big. Course I have no idea what im doing. It just seems like if I am getting just a drip drip drip coming out...i would not be able to have a 200gph pump.

Any suggestions?

You can use a Hammerhead - there is a valve in the effluent line that tunes the drips. a mag2-5 sounds right...

Hmm...eduacate me on this. I must be missing something.
Again if the end result is drips...then how can I feed that much water to the reactor.
Looks like it would either blow it apart or burn the pump out :huh:

nah,

the chamber is pressurized from the feed pump (helps dissolve the CO2), your pump won't burn out from that backpressure, and if the reactor falls apart - that would be a new one too.
You want to feed more (volume wise) that you let drip out, creates a nice overpressure inside...

Sweet!
Thanks Robb.

Off to market.

Nope. The Hammerhead is a medium pressure pump and will blow the calcium reactor apart.

You want pressure, but not much. All you need is a constant "push" of water into the reactor. A mag2 equivalent will work just fine.
