The Marineland Penguin 350B Power Filter Strainer catches large debris from your aquarium tank from being pulled into your Power Filter and damaging the motor assembly. Be sure to use the correct intake strainer for your Penguin Filter model.
Be sure to clean out your intake filter regularly to prevent the intake flow from becoming blocked, putting unnecessary strain on your filter. This Intake Strainer is for the Penguin 350B Power Filter only. Use of an improper intake strainer will void your Marineland Power Filter warranty.
