General Operation
Introduction
Your CASCO NANO CUBE is designed for ease of use and to provide optimal
livestock conditions.
The Cube has it’s own filtration sump unit located at the bottom of the rack. The
water is completely separate from that in anything you might have next to it.
The Cube can automatically top-up from your stores freshwater supply. Under
normal operation there is no need to top-up the systems manually, check to see
if your system has been set up this way, you will find a Red ball cock in the
sump, if you press it down water will come out further up the fitting.
Each aquarium compartment has it’s own water supply and drain, however the
corner aquariums do flow through an adjoing one to get back to the sump. Flow
to each Level of the tanks is individually adjustable with the inlet tap.
Switching the systems on and off
The systems are connected to your stores main electrical supplies.
The lights for all the Cube can be switched on and off using the relevant switch in
the filter area under the tanks
The Cube filtration systems are connected to a 24-hour supply and must under
normal circumstances be switched on at all times. Switching off the filtration
system for any significant length of time will be harmful to your fish!
If an individual component needs to be switched off or disconnected, this can be
done via the plug strip mounted at the bottom of each rack above the filter
system:

IMPORTANT –DO NOT touch the plug strip with wet hands! Risk of electric
shock!
Each plug is labelled with the piece of equipment that it supplies:
- System Pump
- UV Filter
- Heater 1
- Heater 2
When you unplug an item, carefully pull the plug towards you. Draw sufficient
cable through over the filter system so that you can lay the plug safely on dry
ground in front of the unit. DO NOT allow the plug to drop into the filter system!
To reconnect the piece of equipment, check the plug is clean and dry and
reverse the above process. Feed excess cable back behind the system and
reconnect the plug. Check that the equipment is operating correctly.
Water Flow
Each aquarium compartment has it’s own Inlet and Outlet. Flow into the
aquarium compartment can be adjusted or shut off by turning the Blue tap. It is
important to check daily that a good flow of filtered water is reaching each
aquarium compartment
IMPORTANT! –DO NOT switch off the taps completely on the same system at
the same time. Doing so will place excess pressure and will damage your
circulation pump.
Water drains out of the aquarium via the black strainer at the back of the tank. It
is important that these are kept clean from debris (daily check). Allowing them to
block up will overflow the aquarium!

Routine Maintenance
Introduction
Your CASCO Nano Cube is designed for ease of use and to provide optimal
livestock conditions. Some simple maintenance of the system is required. By
carrying this out according to the following schedule major problems and
equipment failure can be avoided.
Daily Maintenance Checks and Tasks
The following checks and tasks need to be carried out at least once a day.
It is strongly recommended that the checks be made once at the start and once
at the end of every day.
Aquariums:
General –Check for any signs of water leaks and general good condition and
correct operation of equipment.
Aquarium Water Flow
Check that sufficient water is flowing into every aquarium compartment.
Adjust taps as necessary.
Check that all aquarium outlets
are clear of any debris.
Clean as necessary.
Poor water flow will lead to
low water quality and temperature
fluctuations that can lead to
livestock loss.
Water Temperature
Check the temperature of the water in each tropical system using a glass
thermometer. Tropical freshwater fish should be kept at a constant
temperature of between 25 and 26ºC (77 and 79ºF)
Water Quality
Carry out water quality tests in accordance with your store procedure
schedule for each system and log results.
Livestock Health
Check general livestock health in accordance with your store procedure
schedule for each system and log results.

Filter System:
Clean/Replace Filter Bag
Switch off system first by unplugging the filter pump.
IMPORTANT –DO NOT touch the plug strip with wet hands!
Carefully pull the plug towards you. Draw sufficient cable through over the
filter system so that you can lay the plug safely on dry ground in front of
the unit. DO NOT allow the plug to drop into the filter system!
Wait a few moments to allow the water to stop draining into the filter
system from the Drain Outlet Elbow.
Gently pull the Drain Outlet Elbow towards you. It will slide off the System
Drain Line allowing you to easily remove the filter bag.
Fit a new filter bag from your spare set, Refit the Drain Outlet Elbow and
reconnect the pump. Take a few moments to check that everything is
operating as it should on the restarted system and that water is flowing
correctly to all aquarium compartments.
The dirty filter bags can be turned inside out and cleaned with a hose.
Store the cleaned set of bags safely for the next changeover.
UV Filter
Check that UV Filter is operating.

Filter System Water Level check that there is the correct level of water in
the pump chamber of the filter sump. Insufficient water can cause damage
to the pump and stop the system from running leading to loss of livestock.
Overflow Outlet
Check that the Overflow Outlet in the Filter Pump Chamber is free from
obstruction.
Automatic Top-Up
Check that the Automatic Top-Up is working correctly by pushing down
gently on the red float. Water should come out of the white top up pipe to
fill the pump chamber.

Weekly Maintenance Checks and Tasks
The following checks and tasks need to be carried out at least once a week.
Depending on the amount and type of livestock in your systems it may be
necessary to carry them out more often.
Carry out the following in addition to the daily tasks above.
Check Filter System
Clear any debris that has collected in any area of the filter system. Stones,
gravel, paper, plastic bags etc can all cause the system to stop working or
flood!
Fortnightly Maintenance Checks and Tasks
The following checks and tasks need to be carried out at least once every two
weeks. Depending on the amount and type of livestock in your systems it may be
necessary to carry them out more often.
Carry out the following in addition to the daily & weekly tasks above.
Clean Filter Foam
Unplug the filter pump as detailed above to stop water flowing.
Remove the filter foam blocks and rinse them gently in a bucket of water
removed from the system. In is important NOT to wash them in tap water
as this will kill off the beneficial bacteria that live on the foam.
Replace the cleaned foam and restart the system.
