Water Quality and Water Treatment in Zoos and Aquariums

What is Aquality?

It is the mission of the Aquality initiative to advance and support water quality and water treatment practices in zoos and public aquaria with a view to optimising the environmental conditions of the plants and animals within their care.

The mission of Aquality is realised through three mechanisms:

1. Symposia

Periodic meetings to discuss the development, design, installation, operation and monitoring of aquatic life support systems in zoos and public aquaria.

2. Manual

A single-reference handbook on water treatment and water quality monitoring in zoos and public aquariums. You can learn more about the manual here >>

3. Discussion

An open discussion forum dedicated to water quality and treatment of aquatic systems in zoos and public aquaria. If you would like to join the discussion forum you can email the moderator at
