SunSun HW603 Pre Filter

Boost your aquarium filtration and extend the life of your main filter. The SunSun HW-603 is a multi-stage pre-filter canister designed to trap debris before it reaches your primary filter, improving water clarity and reducing maintenance.

Key Benefits & Features

• Pre-Filtration System – Captures coarse debris and waste before it enters your main filter

• Extends Filter Life – Prevents clogging, reducing the need for frequent cleaning

• Transparent Design – Easily monitor dirt buildup without opening the unit

• Large Media Capacity (~2.3L) – Add extra biological or chemical media for enhanced filtration

• Easy Maintenance – Quick-release valves allow fast cleaning without disrupting your system

• Universal Compatibility – Fits 12mm/16mm tubing (adapters may be needed for larger hoses)

Versatile Filtration Options

• Comes with 3 multi-density sponges (coarse, medium, fine) for effective mechanical filtration

• Can also be filled with ceramic rings, bio-balls, or activated carbon for advanced filtration setups

How It Works
