We have recently introduced a new solution to water pollution called Clinofish. It is a specific type of Zeolite mineral (found in igneous rock) exclusively mined in South Africa, and is a direct substitute for fish pond filter media that scavenges toxic ammonia from pond water.

It is, in the main, a filter medium with both ion exchange and superior mechanical filtration properties, and acts as a filter on the atomic scale by absorbing toxic ammonia from pond water. This is due to a powerful negative charge that exists within the Clinofish structure that attracts positively charged cation contaminants (such as ammonia), and holds them within the Clinofish structure.

Clinofish is also an extremely effective biological media for maximum colonization of useful, nitrifying bacteria directly as a result of it having particles that are not smooth. It goes without saying, that it has large surface areas as a result.

Why to use Clinofish

  • Controls ammonia in aqua culture and fish hatcheries
  • Reduces fish mortality
  • Improves water quality and clarity
  • Maximises fish growth
  • Can be reused after simple regeneration
  • Removes heavy metals and ionic toxins


Clinofish is available in a 25kg bag, and the average sized pond will use two bags.
