I read the intro thread I decided to do a seperate thread so things didn't go off topic. Anyways hello, my name is Charles I have not had a sw before. I have kept many many planted tanks and still have three. I'm pretty well known amongst other plated tank keepers. Well I want to get my sleeves wet and salty. I have a rimless 20L just begging for some sps. I know everyone says bigger is better, I don't really care much about that I will do it in a 20 anyways. I tinker with leds and arduino for other projects. I want to dive right into the controversy and get chewed out right off the bat, so here we go I have every intention of setting up not only a small tank but a canister filter with a external skimmer. What's everyone's thoughts?
