12,000 Gallon Pond Kit

12,000 Gallon Pond Kit

This kit is suitable for ponds up to 12,000 gallons with light to moderate fish loads. It includes a Hakko 120L Air Pump, 40 feet of 1 inch sinking air hose, a Double Air Base with two 9 inch Air Discs (MDB22) . If you have a heavy fish load you may choose to upsize to a multiple pump aeration system. Please call for recommendations.


Our aeration kits combine all your fittings, hoses, air diffusers and Hakko pump to match your requirements. This makes it easy for you to get the right set up for the best results and long term performance. For proper cooling, it is not recommended to use more than 40 feet of 1" hose. If you need to pump air more than 40 feet please upsize your hose or pipe to 1.5 inch. You may use standard 1.5" PVC shc 40. The HK120L outlet fitting and the Air Base are both 1 inch so you will need a special adapter to upsize to the 1.5 ich pipe. Call us if you need help with this adapter.

Shipping is free.

Koi & Pond Tip of the Day
January 21st, 2018
Ponds with vinyl liners or of fiber glass construction tend to show a decrease in alkalinity over time and may need supplements to maintain an acceptable level. Raise alkalinity by adding Calcium Carbonate, concrete blocks, oyster shells, limestone, or even egg shells.
