Wanting to start using CO2, any suggestions for a 55gallon?

Wow loach master that's a whole lot of attitude for someone who doesn't even seem to get the basics. Maybe since the OPs question was about choosing a CO2 set up you could start by describing yours.

Just to let you know, I have the blue light on because the combo makes my fish look awesome! THe plants get plenty from the other bulbs

Ah well i must not be that much of a basics dummy since nobody ripped on my suggestions. Ya'll are just too much on the defense. I say if a method works, don't knock it....
Besides, our original poster has been so quiet, bet a solution has already been reached.

Best wishes to whatever you are growing dude, or dudette.

Peace
