The only difference in my set up is that the output of my filter used to beva spray bar. Now I have the output going straight into the tank. I am also running a significantly higher bubble rate because it's a large tank. The bubbles are unsightly, but I am more concerned that I am wasting co2 and it might not be getting to some of my plants. I can see the bubbles come out of the output and go immediately to the surface of the water. My drop checker is green so I know some co2 is being dissolved. I just feel like it could be better. I am wondering if a larger reactor might help and have been thinking of building a RG style reactor to replace it. I have read that a larger reactor can help co2 dissolve better and when I look at mine, it really it's quite small. am interested in hearing thoughts, opinions, pros/cons from anyone.
I've made all different types of reactors and the only design that worked very well for my sump based setup at the time was a 27in/4in diameter/ with 1/2in in and out reactor.
Cerges are neat and cool looking.. got to give it that. And while I have never used one, based on experience with reactors of similar dimensions it's not very efficient IMO. Sure it can be dialed in to work any tank, but depending on your system the lower flow and/or Co2 rates that is needed to keep bubbles in check. Means longer dissolve rate which- not good for big tanks or sump based systems.
When I say inefficient I mean the time along with Co2 bub rate to get Co2 levels up where it needs to be. Less bubble from the reactor to the surface = more contact time in the chamber = good Co2 dissolution.
Taller and wider with 1/2in and out and your problem will be solved.
