DO NOT STIR YOUR SAND BED! get a few sand shifters starfish, golden head gobies, black sea cucumbers , incorporate a refugium growing macro algaes such as Chaetomorpha., ( depending on your tank size... otherwise buy 2 each to start off with- I get mine from Ah Beng) you can get chaetos to seed your refugium , I harvest weekly so would be able to spare some ) furthermore : Turbo snails more for the glass walls...short hair sea urchins will munch on the rocks.
