BigW sells little packets of rye (or maybe oat) straw specially for
clearing ponds. Mind you, you could by a whole bale of the stuff for much
the same prices as the prettily packages 100g :-)

I'm sure its the fermentation Jonno, because its too much of a coincidence
that it has cleared to its fullest and the straw is now fairly mushy in
the
water.
Where its staying! Don't want to go backwards from here.
Cheers, thanks for the tip. Somewhere in my memory I can recall a decade
or
two back something about a farmer in the UK dropping it accidentl;y from
his
tractor going over his 'pond' (pommie dam?) and leaving it there where it
cleared the blue green algae.

At last my pond water has cleared; no more algae problems.
After using the local wild oats along the back roads of the Hawkesbury
the
femention has worked. A big problem since it is not filtered and has a
couple of resident Koi among other local small fish species and frogs.
I can now enjoy the fish at 15 inches below the surface plus the fery
water
plants etc.
IT WORKS!!


Great it pays to have a good memory.....Thats how I remembered this
method. Never been on a farm in my life but I remember asking why the
straw bales and got the answer you needed. Beats messy and dangerous
chemicals..Why it works, not sure myself. Maybe its as you say
fermentation..........
