Keeping as much debris and waste out of your aquarium is essential for promoting healthy and pristine environment for your marine life. The Trigger System Filter Sock is a 4" felt sock featuring a micron rating of 100 easily capturing any uneaten food, organic waste, debris and other smaller particles. This Filter Sock will also help with preventing larger objects and marine life like Snails and Crabs from getting into and damaging your pump, making it a great addition to any existing freshwater or saltwater filtration sump system.

Overall, using a Filter Sock in your sump filtration will reduce ammonia and nitrates levels simply by reducing the amount of organic waste that is allowed to renter your system, allowing for crystal clear and healthier water.
