Malfunction - Cause - Remedy
Air bubbles in the aquarium
--- Incorrect positioning of the outlet nozzle.
Position the outlet nozzle toward the water surface, so that the air bubbles do not
enter the aquarium.
The SeaSkim produces foam, but it does not rise into the foam chamber
--- Newly equipped aquarium and / or newly installed SeaSkim.
Wait for the run-in period (1-3 days) and/or the occurrence of a higher water
contamination due to stocking with animals.
--- The water level is too low.
Refill the water level in accordance with the marking on the housing.
The skimmed liquid is very clear
--- Newly equipped aquarium and / or newly installed SeaSkim.
Wait for the run-in period (1-3 days) and/or the occurrence of a higher water
contamination due to stocking with animals. As the water contamination increases,
darker foam is being produced.
---The air controller or air pressure controller is open too much.
Reduce the air supply until dark foam is being produced.
--- Insufficient water contamination.
The water contamination by fish determines the colour of the foam. Light stocking =
light foam, heavy stocking = dark foam.
The skimming performance drops after longer operation or is interrupted
--- The air supply is disrupted due to salt crystals or a bent hose.
Clean the air hose with clear water or check the hose guide (See "Maintenance JUWEL
SeaSkim Quarterly").
- The water intake is dirty.
Clean the water intake.
--- The pump is dirty or defective.
Remove, open and clean with the brush. Replace the impeller if applicable.
The skimmer is noisy
--- The pump is dirty or defective.
Remove, open and clean the pump. Replace the impeller if applicable.
The foam collector fills up too quickly
---The air controller is open too much.
Reduce the air supply at the air controller and adjust the air-water mixture. Proceed in
small steps only.
Excessive quantity of air bubbles in the aquarium
---The air controller is open too much.
Reduce the air supply at the air controller and air pressure controller. Proceed in small
steps only.
