I like the In-Wall Peninsula style myself.

This is a friend of mines tank running SolaTubes. He owns a furniture store and this is in his store. OLD tank shots though, he really needs to get new ones because his corals are insane.. huge and super colorful just in the last 3-4 months... He gets in 3 months the same growth it takes me a year to get. If you look closely you will notice something missing.. powerheads. He only has his return and a OM4-Way on a closed loop and his flow is insane in his tank.
