Hi Muffin

JFYI the reason you have string algae in the first place is probably from
suspended nutrients in the water column, more than likely elevated Iron
levels, hence the string algae. The reason Koi clay helps to combat string
algae is because the clay will bind the iron! The iron has probably come
from water runoff or from pot plant/garden soil. Next time you plant some
more pots in your pond put a layer of clay at the bottom, this will further
help to reduce suspended iron and your plants will go gangbusters for it.

I am posting this in case someone does not know of this.
If I had not seem it myslef,, I'd still be skeptical, (from reading on
other
groups)

you use Koi Clay!!

yesterday I noticed I had hundreds of strands of this stuff growing, (
there
were only a couple LONG pieces last week, but I ignored them), so I
figured
I better do 'something'.
I put in Koi Clay last night & *WOW* it has all dissapeared! I am
stunned!!
(other ponders say it takes several days to get rid of it)

it was suggested for 2 Tablespoons per thousand gal. ( I only put in 1 T.
per thousand) and have read different directions as to every day or every
other day.

Koi Clay is supposed to be very beneficial for your pond ( besides the
Koi).

(I bought mine last year , but it was packed away all winter, ebay is a
good
source, Calcium Bentonite)
