Hi, long time lurker first time poster. Just a little about myself. I have a 55 gl tank with Eheim 2217 T8 strip light. My inhabitants are 4 apistos 3 otos 2 nerite snails 3 red shrimp. I also have various plants and moss. I am not totally new to the aquarium game. However I want to up my game. So with that said I was going to ask some questions and see what answers I find. My questions are about co2 just wanted to know what forum I should post in, don't want to start trouble posting in the wrong section.
Thanks
