Airmax 2" Air Stones – 2-Pack

Fresh air stones bring back the fine, steady bubbles your aerator made when it was new.

Air stones slowly clog with minerals and algae. When the bubbles get weak or uneven, the stone is usually the cause, not the pump. Swapping in new stones before winter is the cheapest way to make sure your aerator keeps a hole open in the ice.

Best for

• Replacing worn or clogged 2 inch air stones, the size used in PondAir aeration kits
• Keeping a spare set on hand for mid-winter

Details

• Pack of 2 round air stones
• 2 inch diameter

Winter tip: Set the stones on a shelf about a foot below the surface, not at the deepest point, so the warmer water at the bottom stays undisturbed for resting fish.
