READ AND FOLLOW ALL
SAFETY INSTRUCTIONS
DANGER – To avoid possible electric shock, special care should be taken in the use of aquarium equipment. For each of the following
situations, do not attempt repairs yourself; contact an authorized service facility for service.
1. A. If an appliance falls into the water, DON'T reach for it! First unplug it and then retrieve it. If electrical components of the unit get wet,
unplug this equipment immediately.
B. If the equipment shows any sign of abnormal water leakage, immediately turn off power at main disconnect.
C. Carefully examine the equipment after installation. It should not be plugged in if there is water on parts not intended to be wet.
D. Do not operate any equipment if it has a damaged cord or plug, or if it is malfunctioning or if it is damaged in any manner.
E.To avoid the possibility of the plug or receptacle getting wet, position
tank to one side of a wall mounted receptacle to prevent water from
dripping onto the receptacle or plug.A "drip loop", shown in the
Illustration at right should be arranged bythe user for eachcord
connecting equipment to a receptacle.The "drip loop" is that part of the
cord below the level of the receptacle or the connector, if an extension
cord is used, to prevent water traveling along the cord and coming in
contact with the receptacle. If the plug or receptacle does get wet,
DON'T unplug the cord. Disconnect the fuse or circuit breaker that
supplies power to the appliance.Then unplug and examine for
presence of water in the receptacle.
2. Close supervision is necessary when any equipment is used by or
near children.
3. To avoid injury, do not contact moving parts or hot parts such as heaters, reflectors, lamp bulbs, etc.

This manual will provide you with the information you need to successfully
operate and maintain your BIO-Wheel System. Please read it carefully and keep
it for future reference.
The Marineland ML-24BW(1) System is an easy-to-maintain, refrigerated and ideal for
displaying and holding live seafood. Dual mechanical/chemical filtration and powerful
commercial BIO-Wheel wet/dry biological filter ensure optimum water quality at all
times.And the compact plumbing design allows for convenient self-contained installation.
Your ML-24BW(1) system comes complete with everything you need to become
fully operational:
Consumables: • Carbon Filtration Pack (#CS1826)
•Prefilter Pad (#CS1859)
•Biological Filter Material #2 (Dolomite: #C0402)
•Instant Ocean®Lobster Salt (#CS0309)
Accessories: • Hydrometer (#CA1501)
•Thermometer (#CA1502)
•Lobster Rake (#CA1503)
NOTE:Toprepare for the possibility of extra water changes, we recommend the
purchase of additional Instant Ocean Lobster Salt (enough for two water changes).

• Reverse Flow Filtration prevents compacting of the filter bed, ensuring cleaner water and eliminating
the need for periodic filter bed maintenance.
•The thermostatically controlled Refrigeration Unit is capable of maintaining tank temperatures
of 45-70˚F and can be preset to the exact temperature required by the system.
•The Protein Skimmer employs heavy aeration to remove dissolved organic matter from the tank in the
form of foam.The foam is flushed from the system and deposited into a floor drain or waste container.
•The Sump Level Indicator Light is located inside the displaytank and to one side. It will glow red if water
in the Sump drops belowdesired level.
In this closed system, prefiltered water exits the enclosed Sump beneath the BIO-Wheel
Filtration Module and flows to the Water Pump. From there, water is pumped through
both the Protein Skimmer and the UltraViolet (UV) Disinfection Unit, then to the display
tank via spray bar and filter bed.
Water entering through the spray bar provides surface agitation, while water passing
up through the filter bed is chilled to proper temperature by the refrigeration coils and
pH-conditioned by the Biological Filter Material #2 (dolomite).Water is then drawn from
the display tank through surface and bottom skimmers and routed directly to the
BIO-Wheel Filtration Module.
As water passes through the Filtration Module, mechanical and chemical filtration is
provided by a Polyfiber Prefilter Pad and Carbon Filter Pack. Containing a pound of Black
Diamond Activated Carbon, the Pack adsorbs dissolved organic compounds which cause
odor and discoloration.
Passing through the Filter Media Trays, filtered water spills onto the BIO-Wheel mounted
below. Because system flow causes it to rotate, the BIO-Wheel is constantly exposed to
both water and air, thus developing a thriving culture of aerobic nitrifying bacteria.
This biocultureefficiently oxidizes all ammonia and nitrite on contact.
From the BIO-Wheel, prefiltered water re-enters the enclosed Sump for recirculation.

INSTALLATION
Tank Preparation
1. Locate unit near a 110–120 volt grounded
outlet with a 20 amp dedicated circuit.
2. Make sure Vented Panel is not obstructed.
(To avoid overheating, we recommend
keeping an adequate distance between
the vent and anybarriersfor ventilation.)
These panels allowcooling air to reach
compressor. Theyalso provide access
to filters, thermostat, on/off switch, drains
and other components.
3. Unpack all accessories, supplies and upper
false bottom from tank. Remove plywood
used for shipping support.
4. Remove Vented Panels. Make sure system
components are plugged into junction box.
5. Connect Foam Drain Tube (see exploded
view Pg. 5) to Drain Outlet or Skimmer Cup.
Because the Foam Drain Tube is designed to
drain off excess liquids and foam from display
tank, you will need to locate tube over a
container or floor drain.
6. Set thermostat (see exploded for location) 50° F.
See page 17 for loading temperatures.
WARNING: Do not attempt to operate unit on
extension cord or non-grounded circuit.
Do not handle or connect plug with wet hands.
The following simple steps are required to get your system up and operational.
Consult exploded view (Pg. 5) for any necessary clarification.

FILTRATIONPREPARATION
NOTE: Ammonia (produced from animal waste and respiration) is the biggest
killer of aquatic animals. For this reason, biological filtration is critical.
Abiological filter is a living filter...aerobic beneficial bacteria that consume animal
waste products and convert toxic ammonia to non-toxic nitrate.When properly
maintained, it keeps your product alive and healthy, your water clear.When a biological
filter is overtaxed or abused, water clarity and product longevity will be affected.
Use of precultured BIO-Wheels (optional) means no need for a lengthy (6-8 week)
break in period.Your bacteria culture is in place, ready to go to work. Product can
be immediately loaded and displayed.
We recommend that you make an effort to keep your lobster population relatively
constant. Beneficial bacteria breathe oxygen, but consume ammonia. No animals,
no ammonia. No ammonia, no bacteria.
IMPORTANT: Your system contains five types of filters:
1. Mechanical –Filter pads to screen out solid waste particles.
2. Chemical –Premium Activated Carbon to adsorb dissolved contaminants,
discoloration, odors, toxic gases.
3. Biological –BIO-Wheels and dolomite to remove toxic ammonia and nitrites and
help maintain pH balance.
4. Protein Skimmer to drive dissolved organic matter from water as foam.
5. UV Disinfection Unit to eliminate waterborne bacteria, viruses and algae spores.
NEVER use soap or cleansers in or around tank.
NEVER leave tank turned off for long periods of time.
NEVER let a BIO-Wheel or gravel bed dry out.
1. Remove Filtration Module Cover.
2. RemovePrefilter Pad and packaged Carbon
Filter Pack. Set aside.
3. Lift out Upper Filter Media Tray and set aside.
Prior to system startup, follow the few easy steps outlined below to get
your system ready for operation. Refer to the Exploded View (pg. 5)
for additional clarification.
PLEASE NOTE: BIO-Wheel Filtration Module for the ML-24BW(1)
is located in the display tank in the Filtration Module and accessible
from the top back side of the display (see Exploded View, pg. 5).

1. Make sure both drain valves are closed
(perpendicular to flow tube) (A). Make sure
return valves are open (parallel to flow tube) (B).
2. Fill displaytank until Sump Water Level
Indicator at side of Filtration Module rises
to Sump Maximum Water Level (indicated).
Never allow water level to go below
indicated Sump Minimum Water Level.
3. Start system. Plug power cord into 110-120v
dedicated outlet and turn switch on.
Never attempt to plug in unit unless
hands and plug are absolutely dry.
NOTE: After startup, additional water will
be needed to achieve proper water level.
SYSTEMSTARTUP
For Saltwater Systems Only: Add approximately 30 pounds of Marineland’s Instant
Ocean®Lobster Salt to tank. Save the remainder to adjust salinity at a later time.
NOTE: When filling tank, run cold water through salt to dissolve it faster.
1. Remove Hydrometer from plastic tube.
2. Rinse plastic tube and fill it with water from tank.
3. Place Hydrometer in tube and tap tube
lightly so that hydrometer floats.
NOTE: You may also float Hydrometer in tank.
4. Read scale on Hydrometer.Reading should be
between 1.020 and 1.025. If the reading is below
1.020,add salt; above 1.025,drain some water and
replace with fresh water.1.022 is ideal.
MEASURINGSALINITY
After your system has been running for about two hours and water
is clear, it is time to measure the tank’s salt level.
When replacing water lost due to evaporation, simply add cold, clean tap water.
If water is removed for a specific purpose, e.g. to dip lobstersor clean tank, new
salt and water will be needed.
Always wait for salt to dissolve before taking Hydrometer reading.
Never pour newsalt into tank if lobstersarepresent. Use a clean container to dissolve
salt (approximately1.5 lbs of salt to every5gallons of water).

AFTER24HOURS...
BIO-Wheels are the newest innovation in live seafood holding system filtration. A BIO-Wheel is
the ideal culture site for beneficial bacteria…bacteria that eliminate toxic ammonia on contact.
If you have ordered a precultured BIO-Wheel, it will be delivered in a separate container on a
prearranged date. At that time, you should first install the BIO-Wheel Module and then add product.
Remember…the ML-24BW(1) BIO-Wheel Filtration module is located in the display tank.

ADDINGANIMALS
Set salinity (1.020-1.025). Adjust water temperature
(50°F). Before introducing new lobsters into the system,
dip each lobster thoroughly in a bucket of saltwater.
Dipping removes accumulated shipping debris and
prevents lobsters from fouling tank.
NOTE: Do not leave lobsters unattended in purging
container for any length of time without oxygenating
water.They may suffocate.
Never use fresh water for lobster dips…
it will kill the lobsters.
For best results, rinse water should be taken from the established display tank,
discarded after use and replenished according to guidelines on pg. 13.
Lobsters
Because fin fish are susceptible to temperature shock,it is important to avoid placing new
fish in water with a temperature much different than that in which they were shipped.
One day prior to the arrival of new fin fish, water in the display tank should be set to
the expected temperature of the water in the delivery vehicle. After fish are added,
reset the thermostat and bring the water down to a proper setting of 50°F.
NOTE: Due to water conditions in some areas, it may be necessary to perform
weekly water changes for fresh water tanks.
Fin Fish
Recommended temperature setting is for North American Lobster (Homarus Americanus)
and some fin fish.When using tanks for other species, adjust temperature as necessary
for that particular species.
9. Place Upper BIO-Wheel Housing over
BIO-Wheel and on top of Bottom
BIO-Wheel Housing.
NOTE: Housings are not interchangeable.
Holes in Upper Housing allow water flow
to BIO-Wheel.
10. Install Lower Filter Media Tray and replace
rinsed Carbon Filter Pack inside.
11. Install Upper Filter Media Tray and replace
blue polyfiber Prefilter Pad inside. Replace
Filtration Module Cover.
12. Restart system.

MAINTENANCE
Routine maintenance must be performed.The procedures listed below are neither
difficult nor time consuming.They will keep your system clean, your stock healthy.
Failure to follow these simple maintenance steps will adversely affect system
performance.This could lead to premature failure of some components and loss
of product.We recommend setting up a maintenance log to track procedure.
Daily
Check Tank for Fatalities and Weak or Damaged Stock. Removeimmediately.
Check Water Pump and BIO-Wheel Operation.
Observe flow of water to the BIO-Wheel Assembly. Make sure that water flow to the
BIO-Wheel is not blocked or restricted in any way.The BIO-Wheel should rotate freely
and remain wet at all times. Speed of rotation is not important. If a BIO-Wheel is
turning - regardless of the rate - it is working.
NOTE:A properly cultured BIO-Wheel is brown or discolored.There is no reason
to clean a BIO-Wheel or replace it - unless it is damaged. If removed from the
system, make sure that it is kept moist and exposed to air until you reinstall it.
If a BIO-Wheel is allowed to dry out or is inadvertantly exposed to a contaminant,
the bioculturemaybe destroyed. A precultured replacement can be purchased
directlyfrom Marineland Customer Service (see back cover).
If water level is low and/or flow interruption is evident, turn off system, make sure all
Inlet Valves are open and check Pump Intake (in Sump) for obstructions. If no obstructions
are found, consult Troubleshooting Guidelines section in this manual.
Every Two Weeks (or as needed)
Clean or Replace BIO-Wheel Prefilter Pads and Replace Carbon Filter Packs.
Clogged filters cannot collect waste. Uncollected waste is returned to the tank and will
reduce system efficiency. In addition, keeping the Prefilter Pad and Carbon Filter Pack
clean and unrestricted is critical to the successful operation of the BIO-Wheel. It must
receive clean, prefiltered water to keep its aerobic bacteria healthy and thriving.
To change Prefilter Pads and Carbon Filter Pack, follow the instructions in the
preceding “Installing BIO-Wheel” section. Rinse or discard used pads. Replace Carbon
Filter Pack and rinse out Filter Trays before replacing.
NOTE: Remember to thoroughly rinse Carbon Filter Pack until water runs clear.
Wipe Down All Exterior Surfaces.
Avinegar/water solution (3 tablespoons vinegar to a pint of water) may be used with
aclean rag or paper towel. Never use chemicals, soaps, detergents or harsh abrasives
on any part of the system. Do not use cleaners inside or near the system at any time.
Inspect Display Tank and Sump for Algae Growth.
Algae spores enter the system naturallyvia tank inhabitants and light allows them
to grow. Although your system’s UV Disinfection Unit works to eliminate algae spores,
the morelight you have, the greater the potential for algae growth.To remove algae,
simplywipe inside tank surface with a cloth, algae scraper or acrylic cleaning pad.
NEVER use soap or metal scouring pads. Keep a dedicated cloth for cleaning the inside
viewing area surfaces. It should be kept clean and isolated from other departments so that
it does not get contaminated by multiple task use.
Never Run Pump Dry!
This will cause it to fail and results in costly replacement.
Warning: Never spray insecticides within 20 feet of your system.
The resulting contamination could kill your product and destroy your
biological filter. If you must use insecticides, be careful to turn off and
cover the system with plastic tarp until the odor has cleared from the
area completely. Then don’t forget to turn the system back on.
