if you're near Costco, it's about 79 cents a quart. Two quarts in my 300 gallon pond every 3 weeks or so keeps the SA to a level where I can easily pick out what remains, but ya wanna know something? When we bought this house 7 years ago, the pond worried me to death. I would never have installed one, given the choice. Now, after 7 years I am much more relaxed I cleaned it yesterday sort of, today I can see some leaves and mud on the bottom, but that's where the fish hide during the winter , as they have little plant cover now. They're happy, I'm happy. And after 3 weeks of clear water, DW is happy!

Whom the gods would destroy, they first give a pond.
