Any CO2 in my tank by doing this method?

[gum]

By chance i broke a pipe on my HOF. As the motor is running, the pipe suck up air into the HOF and i can see bubbles sipping thru the pipe and the whole of my HOF container.

it somehow acts like a reactor lol...

Can i say that CO2 has been mixed in the HOF? My tank level is above the HOF.

If so, can i drill a hole to the HOF and connect a CO2 pipe to it if i have CO2 tank?

Sorry for asking such stupid question..just trying my luck

yes it is like reactor. but not very good if you gonna do it this way.

1: surface to water ratio not so good on a HOF. (think of when water exits the HOF, you lose alot co2 there)
2: there is more wear and tear on the impeller. soon you just might find it dying out on you.

My tank level is above the HOF.

can you elaborate why? is it the UP canister like HOF? if so... point 1 not really in big effect. depends on how your water exits the HOF
