Grech Pond Bio Pressure Filter Replacement UV Tubes

Grech Pond Bio Pressure Filter Replacement UV Tubes

Grech Pond Bio Pressure Filter Replacement UV Tubes are replacement UV-C tubes for the UV unit in a Grech Pond Bio Pressure Filter. They help keep pond water clear by exposing floating algae, viruses and harmful bacteria to UV-C light. They suit pond owners who want to refresh the UV stage of their filter and keep green, murky water under control.

Key Benefits

• Optimal UV-C wavelength, usually around 253.7 nm, to act on floating algae, viruses and harmful bacteria as water passes the tube.
• Premium quartz glass for maximum UV-C penetration and a high level of efficiency.
• Easy to replace. Swapping the old tube for a new one is a simple, straightforward job.
• Designed specifically for Grech Pond Bio Pressure Filters, for a proper fit and the performance the filter was built for.
• Helps protect the look of your pond and the balance of the ecosystem around your fish and other pond life.

Why Regular Replacement Matters

The UV tube in your pond filter works against floating algae, the microscopic plants that can turn pond water green and murky. Over time the efficiency of the tube diminishes, so it becomes less effective against these microorganisms. If floating algae are left unchecked, they can spoil the appearance of the pond. They can also hinder the growth of beneficial pond life, disrupt the ecosystem and potentially harm your fish.

How to Use

• Remove the old tube and fit the new one in its place.
• Replace the tube every 6-12 months as a standard guideline.
• Adjust that interval to your pond. Intensity of sunlight, water quality and the bio-load of the pond all affect how often a tube should be changed.
• Inspect your pond regularly for any noticeable drop in algae control. It is a good sign that the tube may be due for replacement.

Suitable For

• Garden ponds fitted with a Grech Pond Bio Pressure Filter that need a fresh UV tube.
• Pond owners dealing with green, cloudy water caused by floating algae.
• Ponds with strong sunlight exposure or a high bio-load, which may need more frequent tube changes.

Frequently Asked Questions

How often should I replace the UV tube in my Grech pond filter?
A standard guideline is every 6-12 months. Sunlight intensity, water quality and the pond's bio-load can all change this, so check how well your pond is staying clear.

Which wattage do I need for my filter?
The CPF2500, CPF5000 and CPF10000 use an 11 W tube. The CPF15000 uses an 18 W tube and the CPF30000 uses a 55 W tube.

What wavelength do these tubes produce?
They are made to deliver the UV-C wavelength, usually around 253.7 nm, which is used to act on floating algae, viruses and harmful bacteria.

How will I know the tube needs replacing?
Look for a noticeable decrease in algae control, such as water turning green or murky again. Over time the efficiency of a UV tube diminishes, so regular inspection is a good habit.

Is a warranty provided on replacement UV tubes?
No. Every tube is tested by the manufacturer before dispatch, but no guarantee whatsoever is supplied on replacement UV tubes.

Can floating algae really affect my fish?
Left unchecked, floating algae can disrupt the pond ecosystem, hinder the growth of beneficial pond life and potentially harm fish. That is why keeping the UV tube fresh matters.
