Algae on river River Rocks

[Yoji_嬰孩]

I love the natural look. As long as it's not slimy green algae I like it.

but if its really bad, just take a trip out to local carwash and powerwash away.....

I'm always glad when I get a nice coating of algae on the rocks

same here, besides that is what my plecos feed on
