Pondmaster Air Diffusers connects to a pond air pump to introduce more oxygen into your pond. This air diffuser works with 3/4" or 1" tubing.
This air diffuser ring has 48 square inches of active surface area.
Keep the diffuser on the bottom of the pond by filling the supplied nylon bag with gravel.
- Maximum Pressure: 125 psi
- Minimum Recommended Depth: 6"
- Diffuser Surface Area: 48 sq. in.
For Summer Use: The Diffuser will work best when placed at the center in the deepest part of the pond in summer. The rising bubbles will lift and aerate bottom water, allowing oxygen to penetrate sediments and optimize waste decomposition. This will also keep stagnant deoxygenated layers from forming deep in the pond, and effectively circulate the entire pond if properly sized. The Ring Diffuser flowing one cubic foot per minute at 8 ft of depth will effectively aerate up to a 50 foot diameter pond; the shallower the pond, the less diameter can be circulated effectively.
For Winter Use: Your Diffuser is ideal for keeping a hole open in ice during winter, but the Diffuser should not be placed in deep water. Rather, place the Diffuser in weighted Ballast Bag in no more than 16 inches of water at perimeter of pond farthest from deep end or deepest pocket. This will ensure that the circulation from the Diffuser will not supercool the water, which is warmest in the deepest part of the pond.
