Nice set up. I got sick of how inconvenient it is to clean the inside with that small opening. I took a razor to the silicone and took the top off and just use it as a traditional open top tank. Still searching for new lighting as mine came with the 2 x 10w halogens. Currently using it as a QT tank and houses 3 sick Black Phantoms. I have some plants in there now but no real scape. I will redo it once i get new lights and i will add co2 at that time. I got co2 on the 20 tall which i plan to get an actual co2 tank for, then i can use the current paintball tank on the Fluval.
