powerhead co2 diffuser question.

Here is what I am currently using, works like a charm and makes some fine microbubbles that plants like, and with the rotating powerhead it sprays them over a wider area. Had to do a very minor modification due to the size of the rena micro bubbler though.



parts used: powersweep 228 powerhead (prefilter comes with) and 2" rena micro bubbler
