Does anybody (successfully) inject C02 using a power filter, or is a

I do just fine with a Emperor 280 on a 55, a whisper 10-20 on a 29 and a
tiny thing on a 10 gallon. I maintain between they run 15+, 15+ and 24+ PPM
respectively. All three have water levels above the lip on the discharge
chute. I use DIY, 2L/1gal , 2 2L, 2 2qrt bottles respectively.

I run things pretty wide open to maintain these levels.
