Product information

Description

Hagen ClearMax replacement cartridge for Fluval 300G is a dedicated filter media designed to fit Fluval 300G aquarium filters. It combines mechanical and chemical filtration to help reduce dissolved nutrients that promote algae growth, improving water clarity and creating more stable conditions for fish and aquatic plants.

Advantages

The ClearMax cartridge absorbs and traps phosphates, nitrates and nitrites within its structure while providing additional mechanical filtration. Use of this media contributes to clearer water, reduced odors and a lower concentration of nutrients that fuel algal blooms. The cartridge is sized for easy installation and routine replacement in compatible Fluval filter units.

Suitable for

  • Freshwater aquariums with Fluval 300G filters
  • Maintenance routines aimed at reducing algae-promoting nutrients
  • Setups with fish and live aquatic plants requiring stable water clarity

Key specifications

  • Type: Replacement filter cartridge with combined mechanical and chemical media
  • Function: Adsorbs phosphates, nitrates and nitrites; provides particulate removal
  • Compatibility: Designed for use with Fluval 300G aquarium filter models
  • Form factor: Packaged cartridge sized for direct insertion into filter media tray

How to use

Install the ClearMax cartridge following the Fluval 300G filter instructions: remove the old cartridge, place the ClearMax cartridge into the media compartment in the correct orientation, and reassemble the filter. Replace the cartridge at intervals recommended by the Fluval filter manual or when water clarity and nutrient reduction performance decline. Rinse hands before and after handling filter media and avoid squeezing the cartridge to prevent releasing trapped debris back into the aquarium.

Usage recommendations

Replace the ClearMax cartridge as part of regular filter maintenance; combine with routine mechanical cleaning and water changes for optimal control of phosphates and nitrates and to minimise algal growth.
