shaking my canister filter???
Ok guys so here my next question / issue ... well hopefully it is not an issue.
So until I start to diffuse my CO2 in a reactor or something else, I am currently running it directly into the intake feed of my co2 Fluval canister filter. I have heard talk about airlock ... don't know what it exactly is, but today i decided to gently shake the canister filter to see if there was any locked co2 that was not coming out. i shook my canister and a some air bubble did come out.. not a lot.. but a noticeable amount.
Since i have never shook my filter before. i dont know if this is normal?
Were the bubbles co2? if not, is it bad that air is in my filter? how did it get there?
