Carbon doser dial in issue

Arisbel · Sep 5, 2022

I’m extremely confused. For one my alkalinity in my system won’t rise above 6.5 at 20ml from my calcium reactor and the tank is empty with zero corals or fish. It’s a 225 gallon system.

my issue with my particular carbon doser is that it releases so many bubbles at once that makes the bubble dial irrelevant to me. It’s set to 10 seconds per bubble and it’s injecting like 15 bubbles per second. Right now it’s at 12 PSI with a full CO2 tank. I’m using the correct check valve that came with the device which is rated for a minimum of 10 PSI. My calcium reactor is noisy becuase it’s getting filled with too much CO2 so lots of gas moving inside. My pH in the reactor is 6.5 (or atleast that’s what the apex is saying)…

how do I get the carbon doser to inject less bubbles into my system?

Lower the pressure until it just overcomes resistance to bubbles rising in the bubble counter.
Mine ran around 3-4 PSI.
Use glycerin in the bubble counter, it's so much easier to count.

Thank you so much for the tip! Though, no idea how I’m going to get that in the bubble counter. It wasn’t easy to get water in there let alone glycerin.
