Filtration for the penguin pool.

Hi, do anybody could give me some details about pygmy hippo pool filtration system. what is the capacity needed (sand filter) what kind of pre-filtration system needed... I need to precise we are not thinking about an under water viewing exhibit but a much "natural exotic forest pool"...

These are the sand filtration units for the main oceanarium at the Aquarium, there are four in total... The water is pumped from the sea and through a natural filter, the shingle beach the aquarium is suitated next to and into these cylinders filled with sand... The water goes through them at...

This is the filtration system for the salt water crocodile exhibit at the aquarium...
