We carry a large variety and bulk of filter socks and other filter media. Filtration is a key part of a saltwater aquarium, and filter socks do a great job of removing waste and debris from the water colum. If you need poly filter, filter socks, or anything for your aquarium, Fragtastic Reef has what you need in bulk supply.
Using filter socks requires usually a filter sock holder, and we have many different styles and options. Aquarium Filter socks are available in mesh and felt which is the most popular.
