I can't say what is working or not working, but my water is getting clearer.
I did dose with calcite again this week, and I put the McGyver Clay Filter
on-line as well. The water is by no means 'clear', it is still orange, but I
am able to see much further down as of yesterday, and the batting is
definately turning orange.

It poured last night, and will do so again for several days, so I expect I
will be back to square one soon. *laugh*

Maybe just cover your yard in Koi clay instead? It comes in one
ton bags!
