Are you facing these problems?
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.

Why choose Celfish for your aquatic system?

Available in particle size ranges of 0,4 to 1,0 mm, 1,0 to 3,0 mm, 3,0 to 8,0 mm and 8,0 to 16,0 mm.
High selectivity for ammonia, helping control toxic compounds.
Fine particle retention, providing cleaner and clearer water.
Support for colonization by beneficial bacteria, promoting biological filtration.
Triple filtration action: chemical, mechanical and biological, in a single solution.
Ideal for:
- Freshwater or saltwater aquariums
- Ornamental ponds
- Use inside filters or as a substrate
- Fish transport
