Cleaning algea from simulated rock

[jwalk]

I was wonderig if anyone knew the best way to clean algea from a simulated rock finish? I have a small amount of algea growning in the various nooks and crannies of our spa and was wondering if brushing it with straight chlorine would do the trick. Any suggestions?

Brushing with liquid chlorine should do the trick.

Before refilling you can also brush/paint on some algeacide to prevent or slow down regrowth.
