Attn Geo Ca Rector Owners With aquariumplants.com Regulator
 

I have a GEO 612 reactor with an aquariumplants.com regulator. I am having trouble with gas entering the chamber, building up, and slowing down the effluent/lowering the PH. I am almost certain that it's C02 and not air. Right now I have the regulator set at 5.6 PSI and I only need 9 bubbles per minute to maintain a PH of 6.8. The bubble is fairly large and I am wondering if the size of the bubble is causing me problems. Any help is always appreciated.

:beer:

i would say open the effluent a little more and raise the ph some
