The Outdoor Water Solutions 5-Feet Fish Attractor is manufactured in the U.S and made from recycled plastic. It has the ability to promote algae and phytoplankton growth and is 100% non-toxic and safe to fish and the pond environment. It is easy to put together and includes mounting cables so you can attach to your dock, pier or concrete blocks. This product is great in all depths – from 6′ up to 20 or 30 feet. By combining 3 or 4 of these fish attractors together you can create a long-lasting brush pile of protective habitat, protecting small and providing structure for larger fish.
