Hello all

I have been battling this algae for some time now. It is a grean coat
that covers everything including the sand. Its comes off relatively
easy and I have been picking at it every few days to keep as much of
it off the plants as possible.

Any ideas on what kind of algae this is and how do I get rid of it. I
bought a UV sterilizer which will hopefully help. If not I need an
alternative plan.

Please help!!!
