5. Problems

Adjustments: Due to the construction, air and water mixing is automatic, but you

can increase the amount of air and water by removing the grey reduction piece from

the suction side of the pump. Normally no adjustment is required but it may be

necessary to alter the flow control taps (8) to ensure overpumping does not occur

particularly in the start up phase. If still an overflow occurs use the 5-cm elongation

between foam cup and skimmer body.

Air bubbles: Reduce the length of the hose between pump and skimmer. The pump

should be placed close to the surface otherwise more air and less water will be sucked

in because of the increasing water pressure. Result: Many air bubbles are leaving the

skimmer, wet foam will fill the foam cup in a very short time.

If the skimmer is added to an existing aquarium there may be a high concentration of

organic substances already dissolved in the water. This results in very tiny bubbles in

the skimmer. These tiny bubbles remove the organic substances effectively, however

it may be that some of these bubbles are drawn back into the aquarium. After a few

days, the concentration of organic substances will have decreased to such low levels

that this effect will have gone and the water flow is free of air bubbles.

Some types of frozen food may have the same effects. It is best to thaw and wash the

food prior to feeding it to the fish. The air bubbles will stop after a short period by

themselves.

Wet foam. With freshly prepared sea water, after using water conditioners or at

extremely high loading, excessive wet foam may be produced. This wet foam is

forced into the cup, requiring more frequent emptying than normal. After

approximately one day the aquarium load will be normal, and the skimmer will

produce the correct foam.

Dry foam: Not enough foam or too dry a foam could be an indication that the needle

wheel is dirty, or the venturi is obstructed. A thorough cleaning is recommended.

Remove the hose connection from the pressure side of the pump. Move the flap inside

the pump from one side to the other until it can be moved easily (Turn the pump

around and shake it. Now you must hear the flap. If not, clean it again).

Increase the water level inside the skimmer with the two flow control taps. Take the

elongation between foam cup and skimmer and/or the grey reduction piece from the

suction side of the pump away.

6. Maintenance

The collection cup should be cleaned regularly (daily or weekly, depending on the

organic load). The reaction pipe of the skimmer needs to be cleaned only once or

twice a year. The venturi pump should be also cleaned from time to time. The pump

has to be removed and the complete pump housing and the Needle wheel flushed with

clean water. The same procedure should be undertaken with the air injection nozzle.

Don't forget the flap on the pressure side.
