CO2 into a canister filter
I have read several post were people add the CO2 into the intake of the
canister filter instead of using a diffuser. I have just added an Eheim 2215 with a surface extractor. Would adding the CO2 to the intake have any real advantage over the Hagen diffuser I am presently using. It is the diffuser sold with the natural CO2 system, but I am using it with a 5lb bottle. What is the best way to do this? Should I drill a hole in the intake and route the hose it there? If I did this I think it would be difficult to see/count the bubbles. If I anchored the hose below the intake I could count the bubbles, but they may not reliably get sucked into the filter. Any advice is appreciated. Scott |

Any advice is appreciated. Scott I had my CO2 line hooked up to a micro bubbler and then placed under my sponge prefilter on the intake of my Fluval 404. Did not work very well as those CO2 bubbles seemed to gather under the sponge and then burst upwards in a large bubble or two. I took the sponge prefilter off the intake and put the CO2 line directly into the strainer and it seems to work very well other than a constant pfft pfft pfft sound now coming from the Flival which no doubt is the CO2 gas being expelled by the impeller. Works good, after the CO2 has made it's way through all the internal sponges, ceramic rings, bio max etc it is totally dissolved. Rick |

Any advice is appreciated. Scott Take the CO2 tubing and squeeze it between the plastic bars of the canister filter intake strainer. Make sure the tubing runs on the back side of the intake tube so no extra tubing will be visible. You will still be able to count the bubbles by looking at them coming up inside the strainer. No need for a reactor at all. Some filters may collect the CO2 inside the canister. I hear some Eheims are prone to that. The bubbles should completely disolve before hitting the impeller of that canister anyway. |
