aluminum sulfate. it is acid forming so good to use with high pH water. it and a

BV, can't quit now, your just getting started!

I've been meaning to ask the group this for a while: Where is Rod Farlee?
I hope we didn't chase him away with too many water quality questions.

I seem to remember Rod posting one time about suspended clay in pond water.
The clay could be precipitated out with alum, as I recall. Does this sound
familiar to anyone? I think that the hardness of the water had something to
do with it's ability to hold clay in suspension also.

BV, do a seach for water, clay, suspension, alum, precipitate etc. and maybe
you'll come up with something. Keep us posted.
