KW Zone Dophin CF800 Canister Filter with UV - 850 L/h

The KW Zone Dophin CF800 is an external canister filter rated at 850 litres an hour for aquariums up to 90 litres. A built-in 7W UV steriliser runs inline with the filtration, reducing free-swimming algae, bacteria, viruses, fungi and protozoans as the water passes through. It carries a three-layer media bucket, one more than the CF700 and CF1200, so there is room for a chemical stage alongside mechanical and biological.

Key Features

• 850 L/h maximum output, suitable for aquariums up to 90 litres (24 US gallons).
• Built-in 7W UV steriliser that reduces free-swimming algae, bacteria, viruses, fungi and protozoans.
• Three-layer media bucket, allowing mechanical, biological and chemical media to run together.
• Supplied with black sponge and white wool media.
• Quiet operation for display tanks.
• External canister design keeps hardware out of the tank.

Technical Specifications

Setup & Maintenance

Site the canister below the water line of the tank so the siphon primes correctly. Rinse mechanical media in tank water rather than tap water to protect the biological colony. Replace the UV lamp roughly annually, since output drops well before the lamp stops lighting.

Choosing the Right Size

Match the filter to tank volume rather than flow alone. The CF800 suits tanks up to 90 L. The CF700 (750 L/h, to 80 L) sits just below it, while the CF1200 (1200 L/h, to 110 L) and CF2400 (3000 L/h, to 500 L) cover larger setups.

Safety

• Disconnect from the mains before opening the canister or servicing the unit.
• Never run the filter dry. Confirm the canister is primed and full before switching on.
• Do not look directly at the UV lamp while it is lit.
• For indoor aquarium use only.
