Product Information
Full details
The Heissner HLF6000-00 is an all-in-one gravity filtration system perfect for pond owners looking for a simple, effective way to maintain water clarity in garden ponds up to 6,000 litres. It is ideal for hobbyists who want a hassle-free setup, providing a complete package including a pump, UV clarifier, and necessary hoses; however, users should note that the effective capacity drops by half when housing fish, requiring more frequent maintenance in those setups.

FAQs
Can this filter be buried?
This is a gravity filter, meaning the water must flow out of the unit back into the pond by gravity. It should generally be placed at or slightly above the level of the pond water return.
How often do I need to clean the filter media?
This depends on the pond load; generally, clean the sponges every 2-4 weeks. Do not use tap water to clean biological media, as chlorine will kill beneficial bacteria.
Does it come with a pump?
Yes, this is a complete system that includes a dedicated pump, UV clarifier, and connection hose.
Is the UV lamp replaceable?
Yes, the 9W UV lamp is a standard replaceable part that should be swapped annually for maximum efficiency.
Will this filter work for a 5000 litre fish pond?
No, this model is only rated for up to 3,000 litres when fish are present. It would be undersized for a 5,000-litre fish pond.
Troubleshooting
Water appears cloudy or green
Check if the UV lamp is lit; if it is old, replace the bulb. Also, check the filter pads for heavy buildup.
Flow rate has dropped significantly
Inspect the pump intake for debris or clogs and ensure the filter sponges inside the box are not saturated with waste.
Pros and Cons

Setup, Compatibility & Care
Installation is straightforward due to the included components. Connect the pump to the inlet of the filter housing using the supplied hose, ensuring all connections are tightened to prevent leaks. The filter unit must be placed on a level surface. For care, keep the filter unit shaded if possible to prevent excessive heat buildup. The UV bulb should be replaced every season (typically once a year) to ensure it retains its effectiveness against green water. During winter months in colder climates, the filter and pump should be removed from the pond, cleaned thoroughly, and stored in a frost-free area to prevent plastic cracking.
