The Superfish Aqua Flow 50 filter features an 'Easy Click' filter cartridge, making removal and maintenance quick and simple.
These replacement Crystal Clear cartridges are a more advanced cartridge than the standard cartridges. The Crystal Clear cartridge contains sponge media, zeolite, activated carbon and active alumina to help keep your water clear and to help prevent algae growth.
This is a pack of 3 replacement filter cartridges for the Aqua Flow 50 filter pump.
We recommend replacing the filter cartridges once per month to maintain filter performance.
