Ridley Research Aquaria and Algae Culture Facilities
The Ridley Research Aquaria consist of 4 commercially available re-circulating filter
systems. Each individual aquarium can be fully and independently adjusted for
temperature, salinity and photoperiod. The aquaria are filled with artificial seawater
made from Reverse Osmosis filtered tap water and a commercial sea salt. In line
systems include UV sterilisation, trickle bio-tower and fluid sand filtration, protein
skimming and ozonation. The aquaria are suitable as holding and experimental
facilities for temperate and tropical marine organisms including non-native species.
The algal culture facilities allow for batch production of marine and freshwater
microalgae under controlled environmental conditions. Microalgae are grown as larval
feeds and for biotechnology and toxin research.

pump.
Other components
- YSI 5200 recirculating system monitor with multi-probe (temperature,
conductivity, pH, ORP, salinity and dissolved oxygen); control function with
relays for temperature and ORP (ozone).
- Ozone generator connected to protein skimmer for sterilisation and improved
efficiency
- Tricool roof chiller supplying cooler water/glycol mix to plate heat-exchangers
to cool water from the circulation system.
