120 L Hakko Air Pumps for Ponds provide vital oxygen to Ponds. Oxygen is needed for frozen Ponds in the Winter and Ponds depleted of oxygen in the Summer. The addition of oxygen to Pond Water helps keep it clear all year.
Of all the essential elements in water, oxygen is usually in the shortest supply.
HAKKO air pumps can be used to create a huge column of bubbles or “air lift” rising from the bottom of a pond or lake. This brings oxygen depleted water to the surface where the bubbles burst and create tremendous surface turbulence, circulation and aeration. HAKKO air pumps used in this manner will literally breathe life into your pond or lake! They help to prevent stratefication.
Active koi consume 880 mg of O2 per kilogram of body weight per hour at 68 degrees F. After feeding the O2 demand increases. The fish need a lot of oxygen to digest and grow. If there is only 8 mg/liter of oxygen in water, this 16 inch fish would consume all the oxygen in 110 liters (29 gallons) of water in one hour. Well, actually it could be near death in about 45 minutes or less.
