Rex Grigg style, Questions
I am planning on building a Rex Grigg style Co2 reactor and had a few questions
The Tank & sump are approx. 210 gallons with my return pump at 600gph.
I have room for a 30” reactor, is 4” big enough or would I need 6”.
I was thinking of using the suction side of my return pump as the injection site for the Co2, the impeller would chop the bubbles up, and then go into the reactor.
Would vent tubing at the top of the reactor be beneficial, I was thinking I could run airline tubing from the vent to the suction side of my return pump also. That way any Co2 that might collect at the top of the reactor would be recycled through the pump.
Inject the Co2 into the top of the reactor.
Any feedback would be great
