Evo UV Replacement Bulbs

High-Performance T8 UV-C Replacement Lamps for Evolution Aqua UV Clarifiers and Reliable Pond Water Sterilisation

Evo UV Replacement Bulbs are genuine T8 UV-C lamps designed specifically for the full range of Evolution Aqua pond UV clarifiers. These bulbs play a vital role in maintaining clear, healthy pond water by delivering consistent ultraviolet sterilisation that helps control algae blooms, reduce harmful bacteria, and improve overall water clarity.

UV clarifiers are often in continuous operation throughout the pond season, which means the UV-C output naturally declines over time even if the lamp still appears to be functioning. This gradual loss of effectiveness can significantly reduce water clarity and sterilisation performance. For this reason, regular replacement is strongly recommended—typically once per year, ideally in spring—so the system is operating at full strength during peak algae growth periods.

These replacement bulbs are available across multiple wattages and lengths to suit different Evolution Aqua UV models. The 110W system uses a dual-lamp configuration (2 x 55W bulbs), ensuring correct output and compatibility across the range.
