How much air should yo). Since air contains 22% oxygen, aeration adds oxygen to the water . IT IS SO IMPORTANT HOBBYIST UNDERSTAND THE RELATIONSHIP THAT OXYGEN PLAYS IN SETTING UP THE ECO SYSTENE. FIRST, FOR ANY POND, WATER QUALITY...WATER QUALITY....WATER QUALITY.
Example: I put into a 6,000 gallon pond two disk air difusers running on a Hakko 80 L air pump.
With in 3 days this pond was like a New Sparkling System. The water quality is unbelieveable.

TAs temperature increases, water can hold less oxygen.
Most low oxygen problems occur from June through September. The reasons for this are:
- Water can hold less oxygen as it becomes warmer.
- Respiration rates of both plants and animals increase with the warmer water, so more oxygen is used.
- Summer's still, hazy or cloudy days may reduce the amount of oxygen produced.
- Large amounts of feed given to fish at this time of year result in large quantities of fish waste which create a higher demand for oxygen.The last note for safety
NEVER - NEVER install an air pump BELOW water level! (Unless you install a check valve in the line!) If at any time your power supply to your air pump is interrupted, water will back siphon down the delivery tube and flood the pump workings, rendering the pump inoperative, to say nothing of the danger of water and electricity coming in contact.

Membrane diffusers are a great alternative to air stones in many aeration applications. Membranes have hundreds of "I" slots that open as air pressure builds inside of the diffuser. The center of the membrane does not have slots and acts as a check valve when air flow stops. Diffusers have a 3/4" male thread inlet and are 10-1/2" in diameter.
