Hi everyone! I'm new to APC and this is my 1st post. I am a TPT member and posted this question in that forum to solict other's experiences with this kind of set-up. Looking to see if any members here have hooked up their CO2 atomizer on the the intake side of their canister filter. I've had my UpAqua CO2 atomizer aligned between the Cal Aqua X1 glass pipe and the Ehiem 2213 double tap for about 8 weeks now with no issues. The needle valve on my Aquatek mini regulator is set @ 0.4BPS (1 bubble per 2.5 sec) and the water flow on the output side is closed approximately 40%. Takes about 50-55 min for micro bubbles to become visible as water exits the outflow lily pipe in my 12L tank.
Pics to follow.
