Injecting CO2 direct through Rena XP1

[u2_Crazy]

Has anyone injected CO2 direct into the output of the XP1 yet? any ideas which way would be best? TIA

I haven't with the XP1, but I have with the XP2 and XP3. Just run your CO2 into an airstone located under the XP1 intake, and it will suck in the finer bubbles, and you won't have any problems. The finer the bubbles, the better it will be. I prefer Limewood airstones, which you can get online from bigalsonline.com.

Nope, have not had any problems. The XP's have an anti-airlock feature.
