perhaps an odd question but with this material being white, will you try to keep it white and will diatom build up on it? If so will clean up be easy? I know you mentioned that you will have a strong water circulation, will this keep the diatom from building up in odd areas?
That's a great question. I wish it stayed white, but no such luck. Initially, I expect it to reflect what's going on in the tank with brown or green algae. When the tank seasons, I hope it takes on the pink/purple coralline algae look. That's what happened in my other bb tank. Started out ugly, but turned purple after time.
