Injecting CO2 directly into lilly pipe inlet

  • I'm testing to see if we can cut out the diffuser and just feed the CO2 directly into the lilly pipe inlet for my canister filter. I've seen other approaches where people infuse it directly into the canister but I figured, this approach is straight forward and doesn't require any other gear or modifications.

  • You can find the canister filter here And the compatible lilly pipes here

  • I'll create a follow-up post because I too am curious as to how effective the CO2 is dissolving into the water column
