My tank is BB, but it also has a tile bottom. You can get reef safe tiles that would help block light and promote coraline algae growth. I have seen them up to 1'x6". Then you could tape the seems from below or wait for the coraline to take hold to block the rest. My first tank was BB and the fuge light bugged the main tank for a long time until the coraline covered the entire bottom. My 6' 120G cost ~100$ to do with 4"x4" tile.
