About the CUP-7000 Annual Service Kit
The complete annual service for the CUP-7000, in one delivery. Lamp, quartz sleeve, seals and both foam grades are all on the same yearly cycle. Bought separately that is five orders in five parcels, and the seals are the part everyone forgets until the unit leaks.
Contains
- 1 x AllPondSolutions 11w PLS UV bulb, 235mm, 2 pin
- 1 x CUP-7000 replacement quartz sleeve
- 1 x CUP-7000 O-ring pack
- 1 x CUP-7000 yellow fine foam
- 1 x CUP-7000 blue coarse foam
Cheaper than buying the parts separately, and it all arrives together rather than as five parcels.
Important — do not change both foams on the same day
The blue coarse foam holds the bacteria colony that keeps your pond safe. It takes weeks to establish and minutes to throw away. Change both foams together and your pond effectively starts from scratch — ammonia and nitrite climb, and your fish are the ones that suffer.
- Change the yellow fine foam first. It does a mechanical job and holds far less of your colony
- Leave 2 to 4 weeks, then change the blue coarse foam
- Rinse anything you are keeping in pond water only — chlorine from the tap kills bacteria on contact
Lamp specification
- 11w PLS germicidal UV-C lamp
- 235mm overall length
- 2 pin fitting
- Average lifespan approximately 9,000 hours
Fits: AllPondSolutions CUP-7000 all-in-one pond system.
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. Replace it every 12 months for clarification duty, or every 6 months if you are running it for sterilisation.
Clean or replace the quartz sleeve at every lamp change. 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.
