Good idea about using the valves to regulate the flow. Are you just using regular plumbing glue? Thanks for your help. I wasn't thinking of valves so that answers my question about regulating the flow. Wish me luck as this has been never ending to setting up this reactor. Everything seems to have gone wrong. Thanks again.

Yep. Smaller hole (ones supposed to be for air intake) for the feed line. I just use a regular plumbing glue for PVC pipe. The powerhead outlet would be too much for a feed line. I was always worried that the feed line would come off, but so far so good. if I have to do it all again, I would probably use a Heat Shrinkable Sleeve in addition for extra measure.

I use the valve on the powerhead outlet end to control the actual flow to the feed line, and valve on the feed line to tweak actual flow (drip rate or ml/min). Having two valves make things easier.

For my specific system, I am running Co2 at 35 bubble/min. Flow rate at 50 ml/min. I have a Vertex Rx-6D. My system is ~150gallons. Medium stock with mostly SPSs. My water always runs stable at 125ppm / 7dkH.
