Is it possible to have a clean bottom in a BB tank, in a mature system? I hate the look of coralline algae and have always scraped it off of all sides and equipment. Now that I have a BB tank, the coralline is covering the bottom faster than I can scrape it.....plus it gets into areas I can't reach. Should I just give it and let it cover the bottom??

I didn't even realize the urchins ate coralline.....might have to pick on up. Oh well....I guess I let it grow!!!!!!!!
