Surface Skimmer.
Adjust the height of the Surface Skimmer such that normal evaporation will not
cause the water level in the aquarium to drop below the level of the strainer. Err on the side of
caution i.e. set the Surface Skimmer lower than you expect. Setting the Surface Skimmer too high
may result in the water supply to the Prizm being cut off.
8. Flow Adjustment
Initially adjust the Flow with the Flow Regulator so that the water level in the Throat of the
Reaction Chamber is approximately 1 (2.5 cm) below the o-ring and that there are no air bubbles
in the water returning to the aquarium. Due to various aquarium conditions the above setting may
produce a wet instead of dry foam causing "Over skimming", wasting a lot of seawater.
The performance of skimmers are affected by changes in the aquarium water chemistry, which occurs
regularly due to feeding, addition of supplements, changes in salinity due to evaporation, changes
in the bio-load and general tank maintenance.
Monitor the performance of the Prizm, making small adjustments to the flow as necessary. During
approximately the first three days after installation, the Prizm may remove a lot of relatively light
colored waste. As the Prizm cleans up your tank, less, but more concentrated material will be skimmed
off. The daily amount removed will generally stabilize and the ideal flow setting for your aquarium
will be established.
9. Maintenance
To ensure a high skimming efficiency the following maintenance should be carried out on a regular
basis:
The collection cup, especially the part through which the foam rises should be cleaned, since settling
organic matter prevents new foam from rising into the cup. Before removing the Collection Cup
reduce the flow to minimum or switch off the pump. In conjunction with cleaning the Collection Cup,
wipe the Throat of the Reaction Chamber with a tissue to remove settled organic matter.
Cleaning Inlet Pipe:
Disassemble the Inlet Pipe by removing the Air Tube and Flow Regulator as described below and clean
thoroughly with a bottle brush.
To Disassemble:
a.To remove the Flow Regulator rotate and pull the Regulator out of the Inlet Pipe.
b.To remove the Air Tube, first disconnect the Air Tube from the Air Injector nozzle, thereafter
remove the Air Tube connector (with Air Tube attached) by rotating and pulling the connector
out of the Inlet Pipe.
To assemble:
a. Insert the Regulator into the Inlet Pipe by rotating and pushing inward. After inserting check
that the o-ring is seated correctly i.e. in a straight line and in contact with the Inlet Pipe.
b.To replace the Air Tube; attach it to the underside of the Connector, thread the Air Tube into the
Inlet Pipe, push and rotate the connector into position within its housing. After inserting check that
the o-ring is seated correctly i.e. in a straight line and in contact with the Inlet Pipe. Connect the
Air Tube to the Injector Nozzle.
All other parts of the Prizm should be cleaned periodically to remove settled organic matter that will
decompose and pollute the aquarium, this will also prevent clogging and a loss of water pressure.
10. Troubleshooting
Problem: The Inlet Pipe does not fill with water
Solution: Check for the following in order:
l
That the Air plug is closed.
l
That the Impeller is rotating and that the power socket is switched on.
l
There is at least 2 (5 cm) of water in the Reactor so that the Impeller Chamber
is flooded.
l
That the water level in the aquarium or sump is above the inlet of the Inlet pipe
or strainer of the Surface Skimmer.
l
The Inlet Pipe has been assembled correctly and is airtight (o-rings of the Flow
Regulator and Air Plug Connector are seated correctly).

Problem: Water is flowing through the Skimmer but there is no air flow
Solution: Make sure that the Air Plug is open sufficiently. Check that the Flow Regulator is
not almost closed. Check the air path for other blockages.
Problem: The water is flowing very slowly through the Skimmer
Solution: Check that the Flow Regulator is not almost closed Check that there are no other
blockages in the Inlet Pipe.
Problem: The Flow Regulator is fully open but the water level in the Reaction Chamber
does not rise into the Throat
Solution: Rotate the Air Plug slowly in the clockwise direction. A small restriction of the air
inlet will increase the water flow and raise the water level in the Throat.
Problem: The Skimmer is producing a lot of diluted foam
Solution: Reduce the flow through the Skimmer with the Flow Regulator until you obtain the
desired results.
Problem: My aquarium is full of micro bubbles or air mist
Solution: Reduce the flow until air bubbles are not present in the water outflow. Do not
try to run the Skimmer with real wet foam, since this will waste a lot of seawater.
Problem: The Skimmer was working but now there is no water in the Inlet Pipe
Solution: Due to evaporation the water level in the aquarium has dropped below the
height of the water inlet. Adjust the water level in your Aquarium or Sump.
Problem: The bubbles in the Skimmer are too large
Solution: Make sure you are using the Skimmer in saltwater. Skimmers of this design are
not effective for freshwater aquariums.
Problem: Particulate matter is collecting inside the Skimmer
Solution: This is normal however if the quantity is excessive it is time to clean the Main Body.
Problem: The Skimmer is new (or just cleaned), and doesn't seem to be skimming properly
Solution: If it's new, clean it with soap and water and rinse thoroughly with hot water. If it's
just been cleaned re-rinse with water. Allow the skimmer to run for 48 hours before
worrying. Skimmers react to changes in water density; soap and other chemical
residue from the molding process. While this is safe for your aquarium, it does
impede the Skimmer's efficiency for a few days. Allow a 2 day break in time.
