I dropped my CYA sock into the pool. It was mostly dissolved, so I couldn't tell if there was any CYA in it. I dropped it in while untying it, and now there's little white granules floating around in the pool. Not a lot of them, but they exist. Are they harmful to me or the pool if I swim, or can I just ignore them aside from the inevitable minor discomfort from steppage, so long as everyone in the pool rinses off afterward?
