@saltyfilmfolks you were correct a little storing of the sand, a few more snails from my coral qt and the watchman goby that just finished in qt and the sand is as white as it was when I first set the tank up. I have a love hate relationship with the goby, she keeps the sandbed super clean and is a riot to watch. But is always putting sand where I don't want it and moving corals and cuc around to her liking. I guess it is no longer my tank, at least she lets me observe it.
