This sits on the bottom of the pond, or can
be elevated so that the top is level with the water in the pond ..
the top adjusts with the actual level of the water at any given
time under normal use ..
It can be powered by connecting one of the Oase
Aquamax submersible pumps and the ideal model would be the
Aquamax 4000 - then simply connect that pump to the skimmer at the hose
tail connection and your skimmer will be set up and working and we
are sure you would be very pleased with it ..
