Air Supplies.
Everything that connects, distributes, and maintains your aeration system — manifolds to split your airflow, air stones for fine-bubble diffusion, and diaphragm kits to bring a tired pump back to life.
One pump, many stones
A manifold splits your air across multiple stones or diffusers placed around the pond and filter.
Match it to your pump
Smaller Hakkos take a 6- or 12-way; larger HK100–120L pumps need heavy-duty brass or multiple manifolds.
Don't choke the pump
Use all available outlets and vent unused back pressure — never restrict the pump's ability to breathe and cool.
Size your air hose
Use 3/16″ hose for runs under 3 feet and 1/4″ hose up to 5 feet for steady delivery.
Pump running but no air?
That's almost always a worn diaphragm. Precision rebuild kits restore full output and extend pump life.
Watch for blowouts
Frequent diaphragm failures usually point to back pressure — check your air stones for calcium buildup.
