Happet SK-40 - pond skimmer with pump and pre-filter

Leaves, pollen, and insects on the surface of the pond are a daily problem, especially when trees grow nearby. The SK-40 skimmer collects debris from the water surface before it sinks to the bottom and starts to rot. The surface remains clean, the main filter operates more efficiently, and you reach for the net less often.

Key Benefits

• Floating skimmer with floats - automatically adjusts to the changing water level in the tank
• Collects leaves, pollen, and insects from the surface - removes debris before it sinks to the bottom and starts to rot
• Pre-filter traps larger debris - easy to remove and rinse, without getting your hands dirty
• Built-in suction pump - draws water from the surface and passes it through mechanical and biological filters
• Protects fish and aquatic plants - clean, oxygenated water provides better living conditions for pond inhabitants
• Prevents clogging of the main filter - relieves the filtration system and extends the lifespan of filter media

How It Works

The SK-40 skimmer floats freely on the water surface thanks to floats that automatically adjust its position with changing water levels. The built-in pump draws water from the very surface - where leaves, pollen, and bacterial scum accumulate. Debris is trapped by the pre-filter basket and sponge filter insert, and the cleaned water returns to the tank. You can remove and rinse the pre-filter without tools - just once every few days, depending on the intensity of pollution.

Frequently Asked Questions

Does the skimmer work all season or just in summer?
The skimmer can be used throughout the gardening season, from spring to autumn. In winter, when the pond freezes, disconnect it and store it in a frost-free place.

How often should I clean the pre-filter?
It depends on the surroundings of the tank. Near trees that shed leaves - every 2-3 days at the peak of the season. In a less shaded pond, once a week is sufficient. You can remove and rinse the pre-filter under running water.

Does the SK-40 replace the main filter?
No, the skimmer complements filtration, it does not replace it. It collects debris from the surface, relieving the main filter. Both devices should operate simultaneously.
