My personal trainer clients run their business out of their house. They endeavor to maintain a charming and inviting ambience to offer their customers.

It's in a secluded neighborhood but just over a nearby hill is I-280. There's a bit of a soft roar and to mask it they put in a faux waterfall on their sloped front yard, about 15 - 20 feet long, going into a pond with a sump near the bottom of the falls, a round hole in the concrete 20" dia. and 3 feet deep.

I'm redoing the filter setup, the details aren't important, I'm getting into TMI as it is, at any rate, I can't find the material that the pond maker used and he's unavailable, cannot be reached. It looks sort of like coarse steel wool only its made of plastic. It's similar to the washable furnace filters, only more dense. I make break down and use two layers of the furnace filter material.

I've tried nurseries, fountain shops, a large rock dealer, pool shops, Home Depot - no one has it. No doubt someone here knows exactly what it is.
