om...
Thanks for the tip...wow cleaning the pond has really been my last
resort...there are lots of fish and of course I dont want to lose
any...further the task is rather daunting.....previous owners did
not leave much info....so i am going it alone.

I have two quick questions before I resign myself to draining the
pond:

1) Pondzyme (i.e. pond bacteria mixes), Is there a problem if too
much is put into pond...does megadosing bacteria mix in the spring
help water clarity? Would it be dangerous?

2) How about pool type vacuum, that allows vacuuming the bottom
without draining the pond...that said I cannot see the bottom of
the pond.

thanks so much for your help and thanks in advance for any uother
tips

To add to my previous post, you need a very fine filter medium to
filter it out like fine foam, but be prepared for lots of cleaning.
Also make sure the UV is before the filter. Have searched the net
but can find nothing on dosing levels for Pondzyme. I have found the
liquid bacteria better than the powder forms of enzyme, (I use
Blagdon Biosludgebuster, not sure if it is available where you are)
and dose initially once a week for the first month, then a
maintenance dose once a month. My own experience of vacuums is that
they tend to hoover up things like plants and fry best :-)

UV before the filter? Wouldn't the gunk possibly muck up the glass,
deteriorating the power of the UV?

I have mine as follows:

FILTER - UV - Waterfall (Veggi-filter) - Back into pond

No problem with the UV, but green water goes through all but the very
finest mechanical filter medium. If the UV is after the filter it kills
the algae which is then deposited back in the pond if there is no
further filtration. You have in your case, a filter after the UV in the
form of a veggie filter.
