Large co2 bubbles from DIY Cerges style reactor
I set up my pressurized set up on my 125 about a week ago. The regulator/post body is new, but the reactor and plumbing are the same that I used on my 55 for a year or so. The set up worked great on my old tank and I never saw any bubbles. However I am seeing pretty large bubbles coming out of the filter output. When I built the reactor I put a pot scrubber inside to help break up the bubbles. This weekend I plan to take the reactor apart to make sure the scrubber is still intact and to maybe another one (or two) But, I am also wondering if there is anything else that might play a role in this (regulator output pressure, flow, whatever else) For information sake, the reactor is run of my Cascade 1000. The flow goes like this: Cascade 1000 -> Reactor -> eth-300 -> tank.
It's the same filter that I used before. The only difference is that I used to have a spray bar and now it just goes straight into the tank. I used to have and MA957, but built a new setup using an Airgas dual stage regulator. I have the output pressure set to about 20psi. Originally I had it set to around 30psi, but read somewhere that higher pressure can cause large bubbles.
I would assume it has more to do with the spray bar creating enough back pressure to slow down the flow through the reactor and allow proper mixing. now without the back pressure your water is flowing through too fast - I think?
If the back pressure from the spray bar was what causing the better mix than more scrubs may be needed or adding mini bio balls to break up the flow better? Where does the co2 inters? Maybe a Auqa Medic Tee for your co2 to inter before the reactor may help the mix.
