Location and connection
Install the air pump above the water level to avoid back siphoning of the
pond water into the air pump. The air pump should be located on a firm level
surface such as a concrete floor or patio slab so that the air pump does not
vibrate and cause excessive noise.
Connect the small piece of plastic tube to the air pump outlet and then
connect the air divider valve to the other end of the plastic tube. Connect an
air stone to one end of the clear air tube and the other end to the air divider
valve outlet. Repeat for all air stones, ensuring that the outlet valves are in
the fully open position before the air pump is started.
