"Un-smooth" flow of CO2 into diffuser and tank

**neontiger92** · 23rd Oct 2014, 12:11

Hi all!

I have a problem with my co2 flow. Prior refilling my co2 tank, co2 is able to bubble at a constant rate in my bubble counter and into the diffuser.

However, after refilling my co2 tank, the co2 did not maintain the same bps after i have adjusted the rate. For eg. after adjusting my rate to about 2 bps, the co2 will bubble at this rate for about 15-30 mins before stopping and thus cutting off co2 supply to my tank.

Any one has any idea why this is happening? It has been happening for a week and i am not able to figure out why.

What diffuser are you using? Inline diffuser?

I am using a nano glass diffuser in my tank.

Check that the Co2 tanks main valve on top is fully open, not partially.

Check the bubble counter is not leaking, especially its bottom connection to the needle valve.

Also check that the glass diffuser ceramic is clean and not clogged up, maybe wash it and soak in some hydrogen peroxide (H2O2) to get rid of accumulated dirt or algae, see if it helps.

I have opened the main valve fully. I recently soaked my ceramic diffuser in bleach to clear the algae. I will need to check on the bubble counter and maybe change the tubings.
