 Aeration

• Subsurface
• Carries warm water from the bottom of the water to the surface preventing ice build-up.
• Surface Aeration
• Max water flow and oxygen transfer.
• Uses: Fish Pond, Docks, Boat Houses

 Circulator

• Circulators circulate warm water from the bottom of the water to the surface of the water. 
• It also can spread water laterally to push ice away from a dock system.
• Uses: Docks, and Boat Houses

 Tips

• When using circulators, use timers or temperature sensors.
• Setup your de-ice system appropriately.  
• For a personal dock, keep a narrow body of water around the dock open.
• Use circulators to keep ice from hitting a dock on a river.
• Use de-icers to keep a marina clear of ice.
• Verify run times. You may only need to run your de-icer 2-4 hours per day depending on the de-icing situation.
• Check with your state for permits and signage.
