Hi Guys, Looking to purchase an in line Co2 diffuser to go onto the inlet pipe of my standard external canister filter. This filter then goes via a UV up to a top tank six foot up where the tube is under the water surface. I was thinking this would enable as much Co2 to be absorbed as posible into the water stream.

Does anybody know of any good products out there and where to purchase.

Any thoughts much appriciated.

Inline Diffusors....
You can build one out of PVC or buy one of these

Needle wheel bumps also work well.

I have a couple extra PVC reactors around I could sell you. I even have one made of Clear PVC. Let me know if you are interested.

Most people put inline CO2 equipment on the outlet of a canister filter

Most put the diffuser on the outlet so as not to inerrupt the siphon.

I just got the CalAqua inline diffusor from Greenleaf and it really does a good job with my Eheim 2217. The diffusor stays clean and by the time it leaves the spraybar the bubbles are mostly all disolved in the water. However, it isn't cheap.
