KW Zone Dophin CO2 Canister Filter Fast Start-Up - 1450 L/h

The KW Zone Dophin CO2 Canister Filter is built for planted aquariums. Rather than bolting a separate CO2 reactor onto the return line, the mixing system is integrated into the canister itself, so dissolved CO2 goes into the tank already blended with the filtered water. This 1450 L/h model is the largest in the CO2 range and suits planted tanks up to 140 litres. The fast start-up primer gets the siphon going with noticeably less effort than a standard primer.

Key Features

• 1450 L/h output at 15W, for planted aquariums up to 140 litres (38 US gallons).
• Built-in CO2 mixing system, removing the need for a separate inline reactor.
• Strong fast start-up primer for easy, quick priming.
• Built-in heater compartment, so the heater comes out of the display tank.
• Mechanical, biological and chemical filtration in one canister.
• Detachable power valve taps for servicing without draining the hoses.

Technical Specifications

Important: CO2 and Heater Notes

• A CO2 cylinder is not included. The filter provides the mixing system; the gas supply is bought separately.
• Do not unplug the filter before disconnecting the CO2 tubes. If you cut the power with the CO2 still connected, water will overflow back through the CO2 intake tube. This is the single most important thing to know about this filter.
• Turn off the CO2 cylinder whenever the system is not in use.
• The heater compartment takes a 22–24 mm heater built to CE or 3C standard. Check the diameter before buying.

Setup & Maintenance

Site the canister below the tank water line so the siphon primes correctly. Rinse mechanical media in tank water rather than tap water to protect the biological colony. Close the valve taps before disconnecting hoses for a service.

Choosing the Right Model

This range comes in three flow rates, each in a fast start-up or common priming version: 950 L/h for tanks to 90 L, 1200 L/h to 120 L, and 1450 L/h to 140 L. Fast start-up costs slightly more and makes priming easier; common priming is the standard mechanism.

Safety

• Disconnect from the mains before opening the canister, after disconnecting the CO2 tubes.
• Never run the filter dry.
• For indoor aquarium use only.
