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
