Are you facing these problems?

  • Ammonia buildup in the water
  • Cloudy water or suspended particles
  • Excess organic matter in the system
  • Poor biological filtration efficiency

Celfish directly addresses these challenges by combining three functions in a single medium: chemical, mechanical and biological. It helps adsorb ammonia, retain particles and support colonization by beneficial bacteria.

How Celfish works

Celfish is a natural zeolite-based filter medium that provides chemical, mechanical and biological filtration in aquatic systems. Through ion exchange, it helps remove ammonia, while its porous structure retains fine particles and promotes colonization by beneficial bacteria, contributing to water quality.
