Rhino Retro 3" Bottom Drain

The latest Aquadyne Retrofit Bottom Drain offers a quality
innovation for a stable and rugged over the liner bottom drain for those
who do not want to install a drain through a liner, or for
pre-constructed ponds that do not have a bottom drain. This drain is
especially useful for pond and aquatic environments that have
pre-existing liner, concrete, or any other situation that would not
allow underground plumbing to be installed.
Simply fill the ballast area of the drain with small stone, sand,
or other heavy inert material. Then attach a suction hose or rigid
plumbing to the side port of the drain and attach to the pump suction
line. Place the drain in the center or the deepest part of the pond so
that the pump can easily suck up suspended solids and debris from the
bottom of the pond. During the winter months, the drain can be easily
moved to a more shallow part of the pond leaving the warmer water in the
lower parts of the pond undisturbed where the fish collect in colder
temperatures.
Keeping solid waste and debris out of your pond is a very important
step toward keeping your fish healthy and preserving your own personal
sanity with regard to maintaining a cleaner pond.
Often too late, pond owners discover that their ponds begin to fill
with leaves, dirt, and debris that require the ponds to be emptied
cleaned and refilled multiple times per year, not to mention having to
take care of the fish when they are out of their home, plus upsetting
the ecology of the pond. A good bottom drain is the first stepin keeping the bottom of your pond cleaner and your pond healthier.
