Green Machines pack three filtration techniques into
a compact box, brushes, foam cartridges and plastic
So Green Machines give ideal water for healthy fish
and, with a Hozelock Cyprio UVC (positioned on the lid)
guaranteed clear water too
They are easy to clean as each filter component can
be taken out for individual washing
Optional Gravity Flow Filters
Green Machines for 9000 litre ponds and larger ponds
are alternatively available in
The pump is located in the filter box. The filter is
in the ground next to the pond. The filter is full of
water at the same level as the pond. Water is pumped
from the filter into the pond and this constantly sucks
more water from the pond under gravity.
The advantage of this method is that there is no shredding
of solids by the pump impeller before water enters the
filter. So it offers better settlement of solids in
the filter. Secondly, the large filter boxes can be
buried right up to the lid and hidden.
How Green Machines
are so effective 1 - Pond water enters through an aerating spray
2 - Brushes separate out larger solids.
3 - The foam cartridges are the first biological
medium. Because they are only taking small solids they
don't block easily.
The water can only flow through these cartridges - full
of beneficial bacteria.
4 - Water passes down the centre of the foam
cartridges, through plastic Biomedia in the lower compartment
and back into the pond.
