LARGE PUBLIC AQUARIUM DISPLAY

 

Location: Zanzibar, Africa
Role in Project: Design, manufacture, build supervision
Year of Build: 2011
Size: 25,000 liters +
Construction: Concrete, Steel and Acrylic
Time in Construction: 6 months
Annual Visitation: N/A

 

 

Features of Note:

• Twin floor to ceiling acrylic viewing panels
• Structure inserted into an existing build - structures remaining separate
• Refugium based Life support system
• Pumping station from the reef
• System had to cope with high levels of phospate found in supply sea water

Challenges of Note:

The local costline is used by locals to farm sea weed. Independent source water testing showed high levels of phosphates, nitrates and organic waste.

 

Reefscape collaborated with local sources to design a nutrient sink to ensure ultral low nutrient conditions were maintained in the aquarium system. Subsequent water tests of the aquarium showed water within the tank to be "cleaner" than the source water.
