Yup... I have my CO2 hose rigged so it enters the bottom of the inlet
strainer. I drilled a small hole in the bottom of the strainer and the tube
fits perfect. I have it positioned so I can manually see how many bubbles a
minute are being released (sucked) into the canister.

I only need about 12-15 bubbles a minute for my 75 gal. tank. Plants are
doing wonderful, and I don't have fluctuations. I don't think there's a
better method out there, and plus it's free. I tried various diffusers, but
all the ones I tried weren't anywhere near efficient as this method. I use
less than half the CO2 I once needed with commercial diffusers.

I'm sure someone makes a good product out there, but I'll never buy one.

Do you mean down at the place where it sucks water in from the tank?

I just feed my CO2 tube into the inlet of my canister filter... This has
been the best method I've seen yet!
