Getting Started
ASSEMBLY PROCEDURES
Below are the main steps to assemble your aquaponics system. Procedures
can occur simultaneously when assistants are available, or each procedure
can be completed before moving onto the next. In most instances, the site and
available space drive which procedures can be completed first before moving
onto the next. Review this entire guide before beginning to ensure that you
understand how to position and connect the different components.
1. Review this guide and all site layout diagrams and prepare the site.
2. Determine the positions of the tanks, float bed, and related plumbing. Allow
space all around the system components for maintenance and harvest
activities. View the layout diagram for a typical layout.
ATTENTION: If you determine that the typical layout is not right for your
aquaponics needs, be aware that changes in this layout may require the
purchase of additional pvc tubing. Tubing can be purchased locally, or
contact your sales representative for additional details.
3. Construct the float bed as shown in the diagrams. Float bed requires a
flat, level surface free of debris and obstructions. Install and assemble
the frame according to instructions. Install the float bed liner.
4. Position the tanks and assemble and install the system plumbing.
NOTE: Tanks when filled are heavy. Position tanks on a solid, level
surface. If a concrete floor is not present, use concrete blocks or similar
pavers to create a solid, level surface for each of the holding tanks.
5. Install the main water pump and connect pump to the tank plumbing.
Consult the services of a certified and competent electrician when
connecting the pump to power. Customer is responsible for supplying a
solid, stable mounting surface for the water pump.
6. Install the air pump, connect air stones, and place stones in tanks and
float bed. Install air pump above the water level in the holding tanks to
prevent siphoning in the event that the air pump shuts down. Customer is
responsible for supplying a solid, stable mounting surface for the air pump.
7. Fill system with water and check for leaks.
8. Prepare the biofiltration tank.
9. Read and follow the care and maintenance information.

Install Float Bed Heat Tubing
In order to maintain a constant water temperature, in many climates it is necessary to heat water. Your float bed includes tubing; however, additional purchase
is required for the remainder of components needed. Contact your sales representative for additional details. Use photos that follow to install tubing.
1. Tape both ends of tubes to prevent
dirt and debris from entering during
installation.
3. Determine a pattern and install tubing
in evenly spaced rows throughout
float bed. Install outside runs close to
frame edge. Allow approximately 10"
between the individual runs of tubing.
2. Determine where you want tubes to
enter and exit float bed and create holes
in rigid board and foil.
ATTENTION: Photos show using
special clips to hold tubing. These are
not supplied. Use the supplied duct tape
and tape tubing to the foil. Once liner is
installed and filled with water, tubing will
not move. Do not use metal wire or
staples to secure tube.
NOTE: Allow a few feet of tube to extend
beyond frame to connect to heating unit.
(Additional purchase required for heating
unit and parts.)
4. After installing tube loops, inspect area
and remove any dirt and debris that
could damage liner material.
5. Continue with the installation of the float
bed liner.
ATTENTION: Regardless of float bed size, follow these general guidelines:
• Maximum length of any tube loop should not exceed 300';
• There should be at least two (2) loops per float bed;
• Loops must be of equal length.
If needed, consult the services of a qualified contractor familiar with
the installation of similar heating systems.

6Once the liner bed is prepared, continue with the installation of the liner. Assistants are required.
1. With assistance, carefully spread the liner
over the assembled frame. Ensure that equal
lengths overhang each end and side.
4. Take two (2) FA4472B Tek screws and two (2)
102921B neo-bonded washers and carefully
secure the liner to the top of the frame.
2. Beginning at one corner, carefully work the
liner into the corner and along the inside of the
base rails.
NOTE: These fasteners will be removed after
the entire liner is in position and the aluminum
retaining strap is prepared for installation.
3. Fold the liner evenly into the corner and up
and over the top of the frame rails. Try to
remove as many wrinkles as possible.
5. Move to another corner and press that liner
into place.
Required Parts:
• 110097S2 Liner (12' x 13')
• FA4472B Tek Screws, 102921B Washers, and 100442 Nut Setter

10. Move to the remaining corners and repeat the
steps to temporarily secure them to the frame.
7. Repeat the steps to secure the liner material.
8. Check the bottom of the liner for wrinkles and
remove these by working the material toward
the free edge of the liner.
11. While the bed continues to fill, remove any
excess material that touches the ground. Allow
8"-10" to remain for the final steps. It will be
used to pull the liner into final position.
9. Start adding water to the float bed to allow the
water to seat the liner inside the frame.
NOTE: Once the liner is fully secured, there
should be no tension on the fasteners. Adding
water now helps to achieve that result.
12. Continue filling until bed is half full.
13. Complete the steps to prepare and install the
aluminum retaining strap.
6. Cut the material as needed to allow it to fit
more evenly at the corners.
ATTENTION: Do not drop any sharp objects
into the bed liner at any time. Contact your
sales representative for products used to
repair damage to the liner if needed.

Prepare and Install Aluminum Retaining Strap
7Take the 112480 aluminum flat stock and mark the mounting hole locations according to the diagram below. Use a 1/4" drill bit to drill the fastener
holes in the center of the stock at 8" on-center. Do not drill these around or on the float bed frame or liner. Doing so can cause filings to drop into the
water. These will damage the water pump once it is installed and running. Drill in a drill press if possible to keep holes uniform. Cut drilled stock to
length as needed during installation. Attach aluminum retaining strap to frame using the FA4472B Tek screws.
Remove Tek screws and
washers before installing the
aluminum retaining straps.
1. Begin at a corner and remove the Tek screw
and washer to install first prepared strap.
4. Apply slight downward force to stretch liner
material and secure strap with Tek screws.
2. Align strap with end of frame and attach using
the FA4472B Tek screw.
5. Continue attaching straps to the frame until
the entire perimeter of the bed liner is secure.
3. Grip edge of bed liner with duck-bill locking
pliers or similar tool.
6. Using a utility knife or scissors, remove excess
bed liner material. Allow 2"-3" to remain below
the edge of the retaining strap.

Prepare the Secondary Filter for the Bioltration Tank
8Prepare Secondary Filter
When installed, the secondary filter helps remove
solids from the water in your aquaponics system.
Place this filter in the biofiltration tank on top of
the netting inside the tank. Complete these steps
to cut the filter from the bulk 112747 material sent
with your system.
1. Take the filter material and spread it out on a
flat, even surface.
2. Next, place a 55 gallon tank on top of the
material to use as a pattern. This tank is larger
than the 30 gallon tank used in the biofiltration
position; using it for the filter pattern will
produce a slightly larger filter to better fit inside
the smaller tank.
3. With the tank in place, use a scissors to
cut around the tank to create the circular
secondary filter.
ATTENTION: The remainder of the material
can be used for additional secondary filters, or
it can be used to cover your fish tanks when
small fish are present.
4. Fold or roll up the remainder of the material for
future use.
5. Set the tank and filter aside until needed and
continue with the next procedure.
