Pond Aeration Micro Bubble Membrane Diffuser Discs are an important component in establishing and maintaining a healthy pond environment. 8" Diffuser disc produces high oxygen transfer micro bubbles to help keep fish healthy and ponds clear.
Increases oxygen levels for healthy and happy fish. Promotes growth of algae-controlling beneficial bacteria. Lowers levels of dissolved toxic gasses and ammonia. Reduces sludge build-up on pond bottoms. Helps maintain an open-water hole in the ice during winter to release trapped toxic gasses.
Aeration Pump is NOT included.

FAQs & Calculations to Help Select the Correct Kit
Rectangular Ponds
Example: A rectangular pond 15’ long, 10’ wide and 1.5’ Deep Pond is...
15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons
Oval Ponds
Example: An oval pond 15’ long, 10’ wide and 1.5’ deep is...
15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons
Round Ponds
Example: 15’ long, 10’ wide and 1.5’ Deep Pond
15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons
Streams
Example: 15’ long, 10’ wide and 1.5’ Deep Pond
15’ x 10’ x 1.5’ x 7.48 = 1683 Gallons
Water Garden, Few Small Goldfish
Example: 2,000 GPH pump for a 3000-gallon pond with 2’ waterfall.
Fish Pond, Several Small Fish
Example: 3,800 GPH pump for a 3000-gallon pond with 2’ waterfall.
Koi Pond, Several Large Fish
Example: 2,000 GPH pump for a 3000-gallon pond with 2’ waterfall.
Calculating Head Height
Example: 3' (vertical height) + 2.5 (25' of tubing) + 2' (for 2 elbows) = 7.5' of Dynamic Head Pressure
Note:It is important to take into consideration while calculating how much flow will be at the top of your waterfall by accounting for the head height due to the laws of fluid dynamics. Please refer to the flow chart above to help choose the correct pump.
