I attached a picture; its not a great picture cause It was a bit hard to get the shot. The rock has a whites ish fuzzy haze/look

The picture posted on reef central looks hairy where the stuff i have looks more like flat white/clear film.
I used a brush to clean the rock and did a 15% water change (RO/DI new cartridges) but it looks like its coming back. Whats driving me crazy is that its only on one rock.
