the barley straw method works fine on large ponds with green water but not
so good whith blanket weed, whould you realy want your garden pond full of
rotting straw? . Also hydrogen peroxide can be poisonous if the
concentration gets to high.

Barley straw is the answer, I cleared a 2 acre lake of algae a couple of
years ago that had gone like pea soup with 2 bales, the EA recommends this
way of treating algae and will give you more info if you need it. they
told
me that as the straw rots it realises hydrogen peroxide and in just tiny
amounts this kills the algae. pull the bales apart and put loose straw in
to
net bags ( I used wire netting ) and place in the water tied to stakes or
bushes all around the lake, the algae will be all gone in a couple of
weeks.
check that the water is not getting extra nutrients such as slurry from
upstream or you will have a constant problem every spring and summer and
may
loose fish due to deoxigenation.

Hi, my friend has a problem with algae in his pond, he wants to know
how
to
get rid of it. Hes bought a remover from the garden centre but it has
failed, someone mentioned barley as a retardant, any ideas on how its
used?

you could take a look at some of the koi web sites. There are some very
effective biological options. I would look for a product called eco-pure
made by kusuri. It works by using bacteria to reduce the nitrate and
phosphate needed by algae. It also reduces sludge and improves water
clarity. www.kusuri.co.uk
