Use the information and diagram below to position the pumps and install
the correct number of air stones in the float bed and correct tanks.
PUMP #2:
Use eight (8) air stones for this float bed. Evenly
position stones throughout the bed.
Do not position any stone
near the main water pump.
Run the tubing along the float
bed frame in a position that is protected from lettuce harvesting
activities and bed maintenance. Connect these to PUMP #2.
IMPORTANT:
Mount PUMP #2 above the level of the water in
the mineralization tank.
PUMP #2:
Use four (4) air stones for mineralization tank.
Run the tubing along the float bed and tank frame. Stones
should reach to the top of the cone section. Connect
these stones to PUMP #2.
PUMP #1:
Use three (3) air stones in each 55 gallon fish-holding tank. Run the
tubing along the tank frame and plumbing. Secure using the plastic ties. Stones
should reach to where the cone section of the tank begins. (See diagram on
previous page.) Stones can be allowed to float or move around in tank. Connect
all stones for the fish-holding tanks to PUMP #1.
IMPORTANT:
Mount PUMP #1 above the level of the water in the holding tanks.
• Use WF1050A 1/4" hose to connect the air
pump to the distribution manifold.
• Use the 111046A 1/8" white UV poly tubing to
connect the air stones to the manifold.
