In total he's got like close to 20+ Bichers between his 180 and 40 gal. I'm not too familier with Bichers but he has several species from what he's told me and from what I've seen. He's got some Platinums as well.
Filteration consist of a Wet&Dry and two Fluval 404 Cannisters. Also a couple of Rio's inside the tank.
He's re-aquascaping his tanks right now but I told him to join so he can post more pix's.
