Hey, All

We've got a ~200 gallon pond with two 9-10 inch goldfish in our backyard. This summer we put in a big rock waterfall, but as nature takes its course, it was covered in thick green algae that is hard to scrub off. The water is clean and we have a UV on in the line, but what else can I do??

I've heard of putting barley straw in the filter but how long/well does that work?

Any other ideas?

Thanks
