How far down? Would you say right where the tee fitting connects to the reducing coupler? Or would having it extend further to where the coupler begins to expand?
Yes, the bubble forming was a Co2 gap. This was when I was using a cerges reactor. I am hoping switching to a rex griggs reactor would prevent this from occurring. I even had valves pre and post cerges reactor and no matter how I adjusted them I just couldn't seem to find the balance of CO2 absorption to achieve a 1 degree PH drop without getting a huge CO2 gap. It was like 3/4 of the reactor.
What do you mean pressure helps? Backpressure post reactor with a valve?
Was I wrong in my assumption that the more CO2 injected means a higher flow needed for fresh water to absorb the C02?
My plan to dial in the rex griggs reactor is to first purge air after initial setup. After the air has been evacuated start injecting CO2. Set input flow to where the CO2 is getting pummeled. Once I begin to see micro bubbles flowing down towards the bottom add backpressure using a valve I will install on the reactor's output. Or at least this is my plan, however, one thing I've learned is nothing ever goes according to plan.
I don't plan to run 24/7. I have a neptune apex and the plan is to inject CO2 at a high rate and have the apex control the Regulator via PH to my target PH range. I will initially set the CO2 to turn on 2 hours prior to lights and monitor how long the reactor takes for CO2 to make the 1 degree PH drop and adjust accordingly. Then start turning bps down until I get the exact amount needed to maintain the PH. So I'm not just dumping CO2 and needing the regulator constantly cycle on and off. This should help prolong the life of the regulator. I'm guessing around 10 bps initially and hopefully, with this reactors efficiency will dial down to 8 bps or maybe even less. I have no doubt that I need a higher bubble count on this size of an aquarium (180g).
I have never had this much trouble setting up a tank before. I have set up many planted tanks but until this one, the largest was a 75g. They were all so easy. I did my research on tanks with sumps and had a really solid plan prior to even getting this aquarium setup. However, like I stated before nothing has gone according to plan with this setup, lol. Not necessarily all bad but has definitely been a learning experience.
