let it suck up the intake of your filter
or
limewood airstone,micro bubbles,let float up into the outflow of your filter

glass diffuser..plug easily though

use a power head to blow the bubbles

My system is kinda complex, but works perfectly...almost no co2 is lost at all. Take a powerhead (in my case, a Rio 400) and point it downwards. Take a water vacuum about 2" in diameter, remove the bottom part (leaving only the round tube), and connect it to the blower part of the powerhead with a rubber connector.
Drill a hole the width of the airline tubing into the side of the vaccum and stick the tube through it. Now take some filter media, filter foam works well, take a chunk and stuff it into the end of the vacuum. Turn on the powerhead and it will break up the co2 as it gets pumped in from the bottle, absorbing it into the water, and almost none is wasted.

It's not real nice lookin or natural, but it gets the job done very well.

I did what legomaniac89 advised it worked great
on the intake of my pump I put some filter media tightly around it that keeps debries from clogging up in the pump and also serves as a filter

Very possibly. I just disconnect the airline from the check valve at night, completely cutting off co2 to the tank. Then I just plug it back in in the morning.

when you disconect the tubing from the check valve you have to close the check valve so the presure of building the building up co2 doesn't do anything

I just always keep the valve open, connected to the end with the powerhead. This way the co2 in the bottle can escape without pressure building up and any leftover co2 in the reactor gets dissolved and can't escape back past the check valve
