The Dophin Hang On Back filter mounts on the rim of the tank rather than inside it, which frees up swimming space and makes servicing a two-minute job. It combines mechanical and biological filtration in one unit, and the cartridge lifts out whole.
Hang the unit on the back rim with the intake reaching well below the water line, and keep the tank topped up so the intake never draws air. When changing the cartridge, keep some of the old media in the chamber for a week or two so the bacterial colony carries over rather than restarting from zero.
