stoney corals are the ones that buildup reefs due to them making a hard inner shell out of the calcium in the water,
Not sure why, I was told to remove my bio balls but I didn't. I have not had more than 10 ppm nitrates in my tank. I know this isn't typical, but as the saying goes, if it's not broke don't fix it. Lol

Can you post a link to this 'pure bio filter'?
