Everything the CUV-207 needs for its annual service, in one delivery. Lamp, quartz sleeve and seals are all wear parts on the same yearly cycle. Bought separately they arrive as three orders in three parcels, and the seals are the part everyone forgets until the unit leaks.

Contains

• 1 x AllPondSolutions 7w PLS UV bulb, 115mm, 2 pin
• 1 x CUV-207 replacement quartz sleeve
• 1 x CUV-2 O-ring set

Cheaper than buying the parts separately, and it all arrives together rather than as three parcels.

Lamp specification

• 7w PLS germicidal UV-C lamp
• 115mm overall length
• 2 pin fitting
• Average lifespan approximately 9,000 hours

Fits: AllPondSolutions CUV-207 UV steriliser, pond or aquarium.

When to replace the lamp

A UV bulb stops working long before it stops glowing. The visible light remains while the invisible UV-C output fades, so a lamp that still lights up can be doing nothing for your water.

• Sterilisation: replace every 6 months (approximately 4,000 hours)
• Pond or aquarium clarification: replace every 12 months (approximately 8,000 hours)

Clean or replace the quartz sleeve at every lamp change - limescale and biofilm on the sleeve block UV-C just as effectively as a dead bulb does. Full step by step in our UV Steriliser Maintenance Guide.

Fitting. Isolate the power supply before opening the unit. Lightly lubricate the O-rings with a silicone-based lubricant on reassembly to keep the seal watertight.
