Calcium reactor

[Btreefing]

I have a geo 618 calcium reactor that the ph is hard to dial in. I get 6.6 - 6.7 on my milwaukee ph probe in the reactor and any time I bump up the low psi to try and make bigger bubbles the reactor fills with to much co2. My settings right now are 6psi, 1 bubble every 2.5 seconds on a carbon doser and dripping 33 ml a minute with a kamoer pump. I'm trying to get to 6.5-6.6 to bump up alk and calcium

What year was the geo made? Prior to the 2019 model, a lot of people have said this is due to the fact that they were designed for pressure as opposed to continuous duty peristaltic pump. Some people burp them and they're fine. Others have to rig up some intricate method of recycling the gas. Co2 is readily dissolved in sea water, are you sure it's not an air leak?

Geo Calcium Reactor filling with Bubbles

I have a Geo Calcium reactor 618. I moved things around in my sump and since then I have had issues with bubbles in my reactor. I have a masterflex pulling from the sump, and pushing through the masterflex. I have rebuilt my DIY CO2 regulator and replaced the solenoid and needle valve and...

I bought it used so it's older, I thought it might be air bubbles so I ran it without adding co2 and it went away. If I add less co2 it doesn't happen
