I’m thinking of draining 2/3 of the water adding the 40 lbs of live sand, letting it settle for an hour and then putting the water back in carefully to not disturb the sandbed. I have about an inch of live sand in there already but I want to keep a wrasse that buries itself so a thicker bed is required. Thoughts or tips? Btw, it’s fine sand so it doesn’t take much to stir it up. See photo of sand.
