4J. Add media to the unit by following steps H, I, J, K, and L in section #1 ( Hanging On
The Aquarium ).
4K. Open the by-pass valve completely.
4L. Carefully adjust the fluidization level by following steps, P, Q, and R in section #1
( Hanging On The Aquarium ).
4M. Partially close the by-pass valve to divert more water into the filter only if proper flu-
idization is not achieved.
5. UNDERNEATH AQUARIUM WITH A CANISTER FILTER
5A. Place filter on base in desired location next to
the canister filter. Position the filter so that it can be
plumbed on the outlet side of the canister filter.
5B. Screw in the plugs on each side of the bottom
manifold. Make sure the plug "O" rings are seated
properly. In most cases, the bottom inlet ports will not
be needed in this type of installation. In steps 5B
through 5#, refer to installation drawings in section
#2 ( Beside The Aquarium ).
5C. Screw in the check valve assembly in top inlet port.
Make sure check valve "O" ring is seated properly.
5D. Wrap teflon tape on the male threads of the two
¾" MPT x ½" barb elbow fittings provided. Wrap each
fitting 5-7 times with teflon tape.
5E. Screw one ¾" MPT x ½" barb elbow fitting into
the check valve assembly located at the top inlet port. Screw in the other elbow fitting into
the outlet port located at the top of the unit.
5F. Turn off the valve on the outlet side of the canister filter and completely drain the flex-
ible tubing on the outlet side of the canister filter. In most cases, it will be necessary to
remove the "U" or "J" tube form the back of the aquarium. Cut the flexible tubing on the
outlet side of the canister filter and plumb in line a by-pass valve and "tee" which will divert
only a portion of the water from the canister filter and into the inlet port on the left side of
the top manifold. Attach hose clamp and tighten accordingly.
5G. Attach one end of the ½" ID x
11
located at the top outlet side of the filter. Attach hose clamp and tighten accordingly.
5H. Place the other end of the tubing up and over the side or back of the aquarium so that
the water returns to the aquarium and agitates the surface to aerate the system. In come
cases, flexible tubing can be attached to a rigid plastic "U" or "J" tube (not supplied in this unit)
that hangs on the aquarium. Attach hose clamp to the rigid tube and tighten accordingly.
5I. Add media to the unit by following steps H, I, J, K. and L in section #1 ( Hanging On
The Aquarium).
5J. Open the by-pass valve completely.
5K. Carefully adjust the fluidization level by following steps, P, Q, and R in section #1
(Hanging On The Aquarium).
5L. Partially close the by-pass valve to direct more water into the filter only if proper flu-
idization is not achieved.
6. CONNECTING MULTIPLE UNITS TOGETHER
6A. Place each filter on a base in desired location next to the aquarium system. Make
sure unit is level on base. If it's more desirable to
hang the filters on the side or back of an aquarium
or reservoir tank, please refer to steps E, F, and G
in section #1 ( Hanging On The Aquarium ).
6B. Screw plug into the top inlet port on each filter.
Screw another plug into the bottom inlet port on the
right side of the last filter in line and the left side of
the first filter in line. Make sure the plug "O" rings
are seated properly.
6C. Screw check valve assembly into the inlet port
on the right side of the bottom manifold of first filter
and the left side of the next filter.
6D. Wrap teflon tape on the male threads of the
two ¾" MPT x ½" barb elbow fittings. Wrap each fit-
ting 5-7 times with teflon tape.
6E. Screw each of the ¾" MPT x ½" barb elbow fit-
tings into the outlet ports on the top side of each fil-
ter. Position the barb portion of the fitting straight up vertically.
6F. Attach one end of the ½" ID x
11
located at the top outlet side of the filter. Place the other end of the tubing up and over the
side or back of the aquarium so that the water returns to the aquarium and agitates the
surface to aerate the system. In some cases, flexible tubing can be attached to a rigid plas-
tic "U" or "J" tube (not supplied in this unit) that hangs on the aquarium. Repeat this for
each filter used. Attach hose clamps where needed and tighten accordingly.
6G. A by-pass valve may be needed depending on what size pump is used. The by-pass
valve will divert only a portion of the water from the pump to the filters. Refer to step 4E in
section #4 ( Underneath Aquarium with a Lifegard System ).
6H. Add media to each filter by following steps H, I, J, K, L, in section #1 ( Hanging On
The Aquarium ).
6I. Open by-pass valve completely.
6J. Carefully adjust the fluidization level of each filter by following the steps P, Q and R in
section #1 ( Hanging On The Aquarium ).
6K. Partially close the by-pass valve to divert more water into the filters only if proper flu-
idization is not achieved.

ADDING REPLACEMENT MEDIA
A. Turn off pump and wait a full 10 minutes for the media to settle into the bottom cham-
ber. If you have lost media, the level of the media will be below the "Media Fill Level" label
located on the right side of the clear chamber.
B. Remove the retainer screws form the flow control valve located at the top outlet side
of the filter.
C. Pull the flow control valve straight up and remove.
D. Pour in the media up to the "Media Fill Level" label on the unit. Wipe off any media that
may be in the valve chamber with a dry cloth. Lubricate the valve and valve chamber with
the Lifegard silicone lubricant supplied with the unit.
E. Install the flow control valve back into the valve chamber making sure the "O" ring is
seated properly and all parts are free of any debris or media.
F. Screw in the two valve retainer screws.
Below Tank Installations
A. Turn off pump to Lifegard Modular System or canister filter.
B. Completely drain flexible tubing on the outlet side of fluidized bed filter.
C. Follow steps A, B, C, D, E, and F in the above section (Adding Replacement Media,
CANISTER
FILTER
Hanging Installations).
ADDITIONAL EQUIPMENT REQUIRED
Additional equipment is needed in order to achieve optimal water quality in your aquari-
um. This is vital to the health of your plants and animals as well as the nitrifying bacteria
in your fluidized bed filter. Accumulation of large amounts of particulate and dissolved
organic material will encourage the growth of other types of bacteria (heterotrophic) that
will compete with the nitrifying bacterial for available space and nutrients. Additional equip-
ment needed to reduce this accumulation of particulate and dissolved organic material will
include the following.
A. MECHANICAL FILTRATION
This type of filter will trap and remove floating debris and should be cleaned routinely. A
prefilter sponge should be attached to the power head pump to trap debris before it enters
the fluidized bed filter.
B. CHEMICAL FILTRATION
This type of filter is usually filled with activated carbon that removes dissolved organic mol-
ecules.
C. AERATION
Additional aeration equipment is needed in order to maintain complete oxygen saturation
in your aquarium system. This can be achieved with an air pump and diffuser as well as
good water movement at the surface of the aquarium. Proper circulation is necessary in
order to achieve oxygen saturation in your aquarium.
D. ULTRAVIOLET STERILIZATION
Ultraviolet sterilizers control the transmission of disease from one fish to another by killing
free floating micro-organisms as they pass through the unit. The nitrifying bacteria are not
killed because they are attached to the media within the fluidized bed filter and are not free
floating. Ultraviolet sterilizers, although optional, should be the final stage of your filtration
system.
pH LEVEL
Nitrifying bacteria produce acids when utilizing the ammonia and nitrite in the water. These
acids decrease the pH in the aquarium and will inhibit the nitrification process when this
value drops below an acceptable level. This will led to a dangerous build up of ammonia!
It is therefore vital that the pH be tested weekly and a proper level is maintained in the
OUT
aquarium. Please contact the dealer in your are for advice in recommending the proper
Plug
additive for maintaining the optimum pH level.
Recommended levels:
pH . . . . . . . . . . . . . . . fresh water . . . .above 6.2
. . . . . . . . . . . . . . . . . salt water . . . . . .8.2 - 8.4
