Well I keep my 1.65 mil gal natural pond pretty well free of algae
with baraclear-80 which is nothing more than common alum bonded with
bentonite clay in pellet form. I use powdered alum in my holding tanks
and outside aquariums with good results. It will make the water cloudy
since its a powder, but it settles out within a few hours just fine.
The pelleted form Baraclear does not cloud water and sinks right to
the bottom, but I did not have sufficient amount of pelleted form on
hand so I tried just the plain powdered alum and it works just fine,
except for initial clouding. And contrary to what you hear alum is not
harmfull to fish any more than any thing else is if its used in the
proper proportions. I would think you can buy alum in any pharmacy in
the UK or anywhere else in the world.
