Great filter cartridges, easy to assemble and use. It keep the water clean and have had no issues with it. I use one cartridge until it's almost falling apart (8 + months) however, as it holds all the beneficial bacteria in it. If I do need to switch to a new cartridge I keep the old cartridge in the tank for a week or two before removing it so that the new cartridge can build up the bacteria faster.
