Below you find helpful information on Aeration
Water Quality

Water aeration is often required in water bodies that suffer from anoxic conditions, usually caused by adjacent human activities such as sewage discharges, agricultural run-off, or over-baiting a fishing lake. Aeration can be achieved through the infusion of air into the bottom of the lake, lagoon or pond.

Dissolved oxygen (DO) is a major contributor to water quality. Not only do fish and other aquatic animals need it, but oxygen breathing aerobic bacteria decompose organic matter. When oxygen concentrations become low, anoxic conditions may develop which can decrease the ability of the water body to support life.


Subsurface aeration

Subsurface aeration seeks to release bubbles at the bottom of the water body and allow them to rise by the force of gravity. Diffused aeration systems utilize bubbles to aerate as well as mix the water. Water displacement from the expulsion of bubbles can cause a mixing action to occur, and the contact between the water and the bubble will result in an oxygen transfer

Fine bubble aeration


  Fine bubble aeration is an efficient technique of aeration in terms of oxygen transfer due to the large collective surface area of its bubbles.
Fine bubble aeration is an efficient way to transfer oxygen to a water body. A compressor on shore pumps air through a hose, which is connected to an underwater aeration unit. Attached to the unit are a number of diffusers. These diffusers come in the shape of discs, plates, tubes or hoses constructed from glass-bonded silica, porous ceramic plastic, PVC or perforated membranes made from EPDM (ethylene propylene diene Monomer) rubber.[2] Air pumped through the diffuser membranes is released into the water. These bubbles are known as fine bubbles. The EPA defines a fine bubble as anything smaller than 2mm in diameter.[5] This type of aeration has a very high oxygen transfer efficiency (OTE), sometimes as high as 15 pounds of oxygen / (horsepower * hour) (9.1 kilograms of oxygen / (kilowatt * hour)).[2] On average, diffused air aeration diffuses approximately 2–4 cfm (cubic feet of air per minute) (56.6-113.3 liters of air per minute), but some operate at levels as low as 1 cfm (28.3 L/min) or as high as 10 cfm (283 L/min).

Fine bubble diffused aeration is able to maximize the surface area of the bubbles and thus transfer more oxygen to the water per bubble. Additionally, smaller bubbles take more time to reach the surface so not only is the surface area maximized but so are the number of seconds each bubble spends in the water, allowing it more time to transfer oxygen to the water. As a general rule, smaller bubbles and a deeper release point will generate a greater oxygen transfer rate.[6]

However, almost all of the oxygen dissolved into the water from an air bubble occurs when the bubble is being formed. Only a negligible amount occurs during the bubbles transit to the surface of the water. This is why an aeration process that makes many small bubbles is better than one that makes fewer larger ones. The breaking up of larger bubbles into smaller ones also repeats this formation and transfer process.


Winter Aeration:    Keep aeration in place throughout the winter months. Bottom diffused aeration helps to keep the water circulating, eliminating fall turnover and fish kills. It can also help to prevent fish from dying under the ice if you live in areas where you have a complete freeze over.

Aeration will give you a head start on algae control next spring by circulating oxygen rich water throughout the entire pond which will increase the amount of beneficial aerobic bacteria present.

If you don’t already have aeration in place, now would be a great time to install it, before the ground freezes up.  

Year round Aeration is always recommended to keep the life of your pond healthy.

​PUMP and KIT Info

All of our Pond systems are perfect for a DO IT YOURSELF person that wants to save money.

We have both brand new systems with cabinets, fans, tubing and diffusers - and rebuilt systems with the bare minimum of no cabinet or fans.

Depending on your budget - any aeration system you choose will prolong the life and enjoyment of your pond or lake!


Our Rebuilt Compressors may show signs of wear I.E. Anodization of metal components, they may be dusty, dirty, discolored, etc. Capacitors, Power Cord, and Motor Mounts are all used as well and may show similar signs of wear but will be in working condition.

NEW Compressors are just that - brand NEW, with new cord, new mounts, new capacitor and fan guards to protect your fingers and anything else!


Self Sink Tube, Diffuser's, tees, clamps, filters, etc are all Brand New never used.


All motors are tested for function before shipping, and should you have any issues once the item arrives just give us a call or send us an email, and we will correct any issues immediately.


The Rebuilt systems do not come with a cabinet - THEY must be protected from any moisture ( Snow, rain, sleet, etc ) they cannot get wet, they are not submersible, they must be protected from the elements.

​We have numerous styles and systems available from a small water garden and fish pond to large multi acre lakes - we have a the perfect system to suit your needs!  If you don't find something you are interested in just send us an email or give us a call!!
