Our onsite aeration assessment services allow our biologists to
measure the dissolved oxygen levels throughout the waterbody to
accurately assess your aeration needs. Additionally, our biologists
will use these numbers to determine what diffusers to use,
placement of the diffusers and your aeration system to
strategically improve water quality.
Aquatic Biologists, Inc. strongly believes in
customizing each diffused aeration system we install to meet the
unique characteristics of the individual waterbody.
Bottom diffused aeration systems are comprised of four
In addition to sales, we also install and service all types of
systems in Wisconsin and northern Illinois.

Each Aqua Bio diffuser utilizes a specially manufactured Porex
tubing to create the formation of fine micro bubbles (50 - 500
microns) in a 360 degree radius around the entire length of tubing.
Stainless steel plate allows for extended life and protection of
the diffuser tubing while maintaining the diffuser above the soft

AquaAir™ provides ponds and lakes with superior aeration,
circulation, and de-stratification. Dissolved oxygen (DO) levels
are increased throughout the entire water column with the use of
bottom-mounted diffusers. The micro-bubbles entrain bottom water
and synergistically lift it to the surface where atmospheric oxygen
is absorbed and then transferred throughout the water column.
AquaAir™ aeration systems offer the following lake and pond
Robust-Aire diffusers create more water flow to aerate your
pond. Diffusers are designed to provide a fine air bubble with the
least amount of pressure. The base is made of thick HDPE plastic
and a locking fill plug allows you to fill it with pea gravel or
other weighted substrate.
It has a raised design that keeps the diffusers performing at an
optimal level above the pond bottom. A durable, bolted, strain
relief attachment ensures that the weighted tubing will not become
detached during installation or maintenance. A check valve with
Viton seals keeps water from entering the tubing when the system is
For best results Kasco Marine recommends using as part a

ABI utilizes rotary vane compressors in most
applications. These compressors are extremely reliable and
can easily last 20 years with simple routine maintenance. Due to
the efficiency of our AquaBio diffusers, we can use a ¼ hp vane
compressor in applications where a ½ or even ¾ hp was needed 5
years ago. This dramatically cuts down on power consumption
and noise levels from the unit.
In deeper water situations, rocking piston compressors can also
be used, where higher pressure is needed.
Directional flow aeration equipment draws
oxygen from above the water's surface through an air-intake tube
powered by a submerged electric motor. The oxygen enters the
propeller chamber, where it is mixed rapidly by a specially
designed propeller. The propeller breaks down the aspirated oxygen
into fine bubbles while mixing them with water entering through the
protected intake chamber. These bubbles are then thrust via the
propeller into the water, providing horizontal circulation of
Aquatic Biologists, Inc. utilizes both Kasco Marine Circulators
& AquaMaster UltiMax Air injectors.
Water movers are great for shallow ponds where diffused aeration
is inefficient. Moving water insures that otherwise stagnant areas
receive oxygenated surface waters. The moving water is also a
deterrent to unwanted algae growth.
Stagnant water contributes to rapid mosquito reproduction,
including those that may carry the West Nile Virus. Creating a
stream environment helps limit mosquito reproduction and thereby
helps control the overall population of mosquitoes in your
Kascos can also be used to reduce organic sediment by moving
oxygenated water toward the bottom of the pond. This replenishes
the bottom oxygen content, and encouraging the growth of microbial
organisms. Kascos can also be used to keep open water during the
winter. They are great for around boat docks.
An optional dock mount is available to attach directly to a boat
dock or a treated 4x4 spike driven into the pond bottom. We
also offer a custom stainless steel spike for areas with sediment
accumulation. They can also be suspended from a float.
Kasco Circulator Features and Benefits
All models include a float and two (or three) 50′ braided nylon
mooring ropes and are available with 50′, 100′, 150′, or 200′
(250′, 300′, 400′, or 500′ for 240V models) SJTOW underwater rated
electrical power cords.
This series of aerators provides horizontal circulation of water
and oxygen at or below the surface. Powered by an exclusive
submerged electric motor, the specifically designed propeller
circulates water directionally. Available in mixer, aspirator,
surface float, or bottom fixed base versions.
ULTIMAX Features and Advantages:
Although not nearly as efficient as diffused air systems,
windmill aerators are a great option for remote ponds. The windmill
can be located hundreds of feet from the pond, allowing placement
in the windiest location. Double diaphragm windmills are also
available, which increase windmill efficiency by 240 percent.
Consult with an ABI representative before utilizing a windmill to
determine if this application fills the aeration needs.
Solar Powered units are available - Consult with an ABI
representative for more information.
Winter aeration will maintain open water. This may pose a
problem to people or animals falling through the ice. Ice domes
solve this problem by allowing the diffused air to escape up
through the dome vent. This allows ice to form around the dome. Ice
domes may also discourage geese from staying around too long in the
