what does potash and epsom salts do for a pond, plants, fish? I've seen
that remark about potash in a couple of spots, and 1)what is it and what
does it do? and 2)where do you get it? and 3) is it ok with fish and plants?

thanks, kym

I built a filter out of 25,000 7.75"x0.125" straws about a month ago and
the water cleared a whole lot over the past few days. I'm not sure if
this has anything to do with it but I also added a bunch of iron,
potash, and epsom salts about a week before it cleared (much more than
anyone here ever suggests).
