I have a one month old pond (1400 US gallons), the waterfall has
developed
what looks like algae on the natural stone I am using for the waterfall.
Is
this in fact algae or something else (moss?) Anyway, is this something I
should try to get rid of or is it harmless? I kinda like the look of it.

Thanks
