The Oase PhosLess Flow 3000 is designed to ensure the cleanliness of your pond water. It works best at a flow rate between 300 l/h and 3,300 l/h. It is recommended to have a flow rate of 300 l/h for every 10,000 litres of pond volume, but if you need a higher flow capacity, you can use multiple cartridges in parallel.
 
The cartridge is easy to install with 2" BSP or 50mm/2" flexi hose connections for in-line installation. It also has the added convenience of being easily back-flushed by reversing the water flow direction.
 
Please note that when choosing a suitable pump for installation, a delivery head of 3m should be taken into account. Also, if the water is unfiltered, it is important to use the Oase Secure Flow 3000 as a pre-filter prior to the Oase PhosLess Flow 3000 to prevent contamination.
