Long term users of crushed coral. Did you ever get coraline algae growing on it? When I considered crushed coral I was afraid of a white bottom turning to purple or green.
I'm a special grade sand user for the aesthetic reasons of having a nice white sandy bottom. I'm also the type of person that scrapes the back glass so it's all black.
