About This

• 【Package Includes】: 9 pieces of fish filter cartridges, compatiable with AQUA-Tech 20-40 & 30-60 power filters (EZ-Change#3) & Marineland Penguin PRO Power Filters 275/375 & Original Penguin Power Filters 200 350 - Rite-Size C.
• 【Full filtration】The filter cartridge has dense filter cotton, which can adsorb all kinds of debris and fish excrement, and the grid design of the fish tank filter cartridge makes full contact between the activated carbon and water to achieve maximum deodorization and water purification, thus giving your lovely pet a fresh and comfortable living environment, and also saving you the time of manually cleaning the fish tank.
• 【Ready to use】Our filter cartridge is already set up, it just needs to be installed correctly on the power filter and it is ready for quick filtration. If there is carbon on the filter cotton, please clean it before use.
• 【Easy to replace】: you can replace the old fish tank filter cartridge without the help of tools. After many tests by our engineers found that the adsorption of activated carbon is limited, it is recommended to replace it in 2-4 weeks to keep the best effect.
• 【Friendly Service】: As a brand seller, we will be responsible for your purchase and promise to give you a two-year warranty from the date of purchase. If you have any problem in understanding or using our aquarium filter cartridge, please don't hesitate to tell us and we will try our best to help you.
