bill the arrows on the valve is to show the flow of the carbon correct?
I think you mean Co2 But yes that is correct the arrows should be pointing towards your reactor's intake for the Co2.

I would say your correct that it's most likely the guages themselves allowing air into the system, But rest assured they will fix it under warranty. I have had mine for quite some time now and it's the best out there.Ive been using a Carbon Doser for about 6 months - It's extremely accurate (paired with a Cole-Parmer peristaltic pump - It's an unbeatable combination.)
I have been having a problem air air leaking into the system. I've been able to confirm it's not coming from the GEO 612 or the water intake, and the CO2 line has been replaced - which leaves the regulator itself. Aquarium plants is trying to help me get it resolved.
You're right Bill - AquariumPlants is advance shipping me a replacement unit. I highly recommend both the Carbon Doser and AquariumPlants.I would say your correct that it's most likely the guages themselves allowing air into the system, But rest assured they will fix it under warranty.

Probably because Aquarium Plants calls the regulator a "Carbon Doser"Kewl
Don't know why I put carbon. Who changed the thread title? Not complaining just wondering.

Just in case this is of value - I've found it requires at least 1.5PSI to defeat the check valve (Aquarium Plants medical grade check-valve.) I can run mine a couple of ways with the same results - 2 SPB (seconds per bubble) @ 2PSI, or 8 SPB at 8PSI (or seemingly anywhere in between with similar ratios.) Using a GEO 612, this maintains a reactor pH of exactly 4.90. With a 25mL/Min effluent rate, my tank is steady at 10.5dKH and 440 Ca (I also use Kalk saturated ATO and a CO2 scrubber to support tank pH.)Bill what's your psi on the low side?

Wow nice detailed post thanks.
At 1st I was thinking the unit needs breaking in because of bubbles bleeding out when I had it on 10psi (that is what it needed to be on my old regulator)
But after reading your post i realized you don't have to have a high psi like 10-15 to get a constant bubble rate like on the conventional regulators.
Am I incorrect?
Edit: the other thing you mentioned was keeping your reactor at a constant ph. I actually have mine fluctuating from 6.6 to 6.5. Should I adjust to have it stay at one ph level?
