My biggest concern with the AS system is that they severely limit your
choices of pond treatments when things go bad. Formalin is an oxidizer, as
is PP, and both are neutralized by the mulm in the pond.

Thanks Jerri & Joe for the additional comments.

It sounds like the fellow I'm advising is doing more researching and
talking to a lot of people so I think he'll be okay. The only thing I'm
hoping is he'll take the advice to wait on the rocks in the pond. We'll
see. ;o) ~ jan
