*by N***L on 17 September 2024*

The filter cartridge arrived promptly the next day to be used in my newly set up fish tank. I was given a used filter from a friend and decided to use new cartridges and media inside. Once out of the pack the quality of the filter is excellent and so easy to install and fit inside of the filter housing. The top unclips which makes it so easy to remove and then clean. Since it has been in use the fish are all happy and healthy so it is doing exactly as it is meant to function. Money well spent on a quality product.
