High-Efficiency Micro Bubble Oxygenation – These pond aeration membrane diffuser discs produce ultra-fine micro bubbles that maximize oxygen transfer, helping keep ponds clear and fish healthy. Available in 5" and 8" sizes to match different aeration needs.
Supports a Healthier Pond Ecosystem – Increased oxygen levels promote beneficial bacteria growth that helps control algae, reduce sludge buildup, and improve overall water clarity without chemicals.
Reduces Harmful Gases Year-Round – Helps lower ammonia and other dissolved toxic gases while improving bottom-to-top water circulation. Also assists in maintaining an open-water hole during winter to release trapped gases.
Durable, Fish-Safe Design (Pump Not Included) – Built for long-term underwater use and safe for all freshwater fish and plants. Designed to pair with compatible aeration systems; aeration pump sold separately.
How Subsurface Aeration Works & Why Your Pond Needs It:
This shows a subsurface aeration system — basically an air pump on shore that sends air through a hose to a diffuser on the pond bottom.
The diffuser releases tiny bubbles that rise to the surface, pulling water up with them. This creates a circulation loop that mixes the entire pond.
Why it matters: Without it, ponds develop a stagnant, oxygen-starved bottom layer. That leads to muck buildup, algae blooms, bad smells, and fish kills.
By circulating water from bottom to top, the system gets oxygen throughout the whole pond. This keeps fish healthy, breaks down muck faster, reduces algae, and keeps the water clean. It's the most effective way to improve overall pond health.
