I use trap door snails to keep my pond clean. They thrive on algae and
don't touch my plants and dead plant material. My fish love the nice
clean water they leave.

Can those be purchased at pet stores?

I bought mine at a pond shop. Here in SE PA our best pond shop is a
great garden center called Black Creek Greenhouse off route 625 in
Lancaster County in the Pennsylvania Dutch area. *It is about a couple
miles north of Shady Maple (rt. 23). It is open from April 1 to July 1,
and is the best place for water plants, Koi, and snails.
