Please specify if metric conversions are required - these will be supplied with your filtration system. The table below can be used to correctly identify the equivalent metric fittings required. It includes the inch names for pipe products (called NPS or "nominal pipe size" and the corresponding metric equivalents (called DN or "diameter nominal").

Installing auto-wash timer valves on a protein skimmer helps to keep the skimmer clean and working efficiently at all times. Up to two automatic valves may be installed - one to wash out the inside of the skimmer cup with salt water and one to wash away discharged foam to waste with freshwater. The frequency and duration of washes can be adjusted to suit.
Ozone can be used to great benefit for improving protein skimmer efficiency and enhancing water clarity. Installing a REDOX monitor ensures that ozone is produced in a controlled manner and the optimum amount of ozone is delivered to the protein skimmer.
An ozone monitor can be used as a fail-safe, ensuring your ozone equipment is functioning correctly and alerting you if ambient ozone levels rise beyond recommended safety levels. Recommended for any installation utilising a 2g or larger ozone generator.
A supply pump is essential for supplying water via UV sterilisers back to a ring-main or back to your tanks. For most applications we recommend a pump capable of turning over the total volume of your system four or five times per hour.
