just leave it, it won't affect your waterquality, but if you do not like the look, get a new nailbrush,and scrub the wood, while holding the hose to extract water close to where you are scrubbing during a waterchange.
Any loose algae will be eveacuated that way.

hi noddy i dont mind the look because it looks natural, i will leave it thanx honey xxxx

as said either leave it or scrub it off
