I think what elaineo was getting at is that if the mold/algae/greenslime grows on the perlite it's going to grow on sand, too. I think what you're trying to do is get something (like sand) that will be less visible/noticeable (smaller grains) and maybe not as white as the perlite that shows a greater contrast between white and green as, say, tan or brown to green...maybe? I get the green perlite down here, too. As long as the plants look okay I'm not really concerned...kind of the natural order of things.
Did I ever mention that I'm a "thinkin' man"?
