AQUAFORTE ECONOMY PLL Bulbs (18w-55w)(Fits Oase)

AquaForte Economy PLL UV Lamps – Replacement UV Bulbs (18W, 24W, 36W, 55W)

Maintain crystal clear, algae-free pond water with the AquaForte Economy PLL UV Lamps, available in 18W, 24W, 36W, and 55W sizes. These cost-effective yet high-performance UV bulbs are designed to work seamlessly with a wide range of pond UVC units, helping you control green water and keep your pond fish healthy.

An essential component of your pond filtration system, UV lamps work by emitting ultraviolet light that neutralises single-celled algae, harmful bacteria, and pathogens that cloud your water. However, even if your bulb still glows, its UV-C output weakens significantly after 8,000–10,000 hours of use. That’s why annual replacement is vital for maintaining effective water sterilisation.

🔍 Size Options & Recommended Usage:

• 18W – Ideal for small garden or ornamental ponds up to ~4,000L

• 24W – Suitable for medium ponds with light to moderate fish stock up to ~6,000L

• 36W – Great for koi and fish ponds up to ~10,000L

• 55W – Designed for large koi ponds and heavily stocked systems up to ~15,000L

Each lamp fits standard PLL UV-C clarifiers and is suitable for pond systems that use pressurised filters, gravity-fed filters, or UV clarifiers as standalone units.

🔧 Compatibility & Installation

These bulbs are compatible with a wide variety of popular UVC systems, including many models from AquaForte, Evolution Aqua, Hozelock, Yamitsu, and others. Please always check the wattage rating on your existing bulb or unit before ordering.

💡 Tip: Replace Annually, Not When It Fails

Even if your bulb still lights up, the invisible UV-C power fades over time, reducing its effectiveness. Replacing your UV lamp once a year—ideally in spring—keeps your pond water at its best during peak algae season.

Choose your desired wattage above and restore clear, healthy water to your pond the efficient and affordable way with AquaForte’s trusted Economy PLL UV lamps.
