are several different diffused aeration kits. Diffused
aeration systems are the best way to aerate, destratify and create
circulation on ponds over 6' deep. Each system has three basic parts.
The air compressor sits on shore and pumps air out through the hose to
the air diffuser located on the bottom of the pond. The result is
thousands of tiny bubbles rushing out of the diffuser to the pond
surface, creating circulation and providing aeration.
There are several advantages to using diffused aeration kits instead of
1.Electric motor is on shore, not in the water,
2.Air diffusers lay on the bottom, ensuring aeration of entire pond
from bottom to top, regardless of depth size,
3.With proper sizing, tubing lengths up to 2000' can be achieved for
ponds without electricity nearby.
All motors are designed for continuous duty operation and are oil-less
for low maintenance. Periodic cleaning of air filter and replacement of
diaphragm and gasket every few years is all that is necessary. Air
stones can be cleaned (if necessary) in muriatic acid to restore
like-new performance. We can build much larger systems or alter these
kits to fit you specific needs. Please call for assistance. Kits
include everything needed for installation and operation except
for tubing weights. Tubing is buoyant and requires a 5# weight every
6-8' sink, or use optional self-weighted tubing.
Fountans vs. Diffused
Aeration - Which is Better?
Fountains are a popular choice when decorative aerator is desired.
Fountains splash the surface of the pond and help control surface algae
and duckweed, but do not aerate down to the bottom of deep ponds. We do
recommend surface or fountain aerators in ponds that have a maximum
depth of 5' or less.
Pond Aerator -
Below we are providing you an illustrated guide on how to properly
install an aeration system. Obviously this is a basic overview and is
not designed to be a comprehensive overview. As you can see installing
our systems is not overly complex and can be easily installed by the
average do-it-yourselfer. Othewise if you do not have the time or
desire to install an aeration system yourself, many of our customers
have had lots of luck hiring independent landscapers, electricians and
plumbers to install these units for a reasonable price.
1 - Unpack your aeration
system and if you see that any parts are pieces are missing please
- After unpacking you willl
want to start by assembling the diffuser. Find this barbed check valve
and determine if your aerator has 3/8'' or 1/2'' tubing. If you have
3/8'' tubing then you can leave the barb as it is. If you have 1/2''
tubing you can remove the tip of the barb fitting at the
line illustrated in this image.
- Find one of the included
hose clamps and slip it over the barbed check valve fitting pictured
above. Then push the tubing tightly on to the barbed fitting and
tighten the hose clamp.
- Utilizing washers on both
sides of the base insert provided bolt and tighten the nut, this clamp
will provide strain relief for the tubing.
- The base of your diffuser
has a special compartment that can be filled with sand or gravel to
help weigh down the diffuser on the bottom of the pond, find the cap of
this compartment and remove it.
- With the cap removed you
can now fill the base with sand or gravel. Once the base is full you
can replace the cap.
- Now you will want to find
the round diffuser head with a male pipe fitting and screw it hand
tight on to the diffuser base.
- Now that your diffuser is
assembled and ready, you can now get the tubing or airline and unroll
the entire roll.
- Tie a loop around the
diffuser with a nylon rope as shown in the image below, this will
assist in lowering the diffuser to the pond bottom in an upright
- Take the diffuser out
into the pond at the desired location, preferably on a boat if you have
one, then hold the unit underwater letting the remaining air escape
from the base.
- Begin to lower the
diffuser to the bottom of the pond, be sure to put most of the weight
on the nylon rope and not on the tubing.
- Once the diffuser is on
the bottom of the pond you can release one end of the rope and pull on
the other side until the rope is out of the water. (Optional you can
leave a rope tied to the diffuser with a duck decoy or something that
will float in order to pick up or move the diffuser at a later time
because if you ever have to move the diffuser you will not want to pull
from the weighted tubing because you could snap the barb fitting)
- If your aeration system
has more then one diffuser then you will install the valved outlet
assembly. This valve system will allow you to control the airflow to
- Once the valved outlet
is installed you can now connect the other end of the airline to the
compressor. The same applies if you have a system with just 1 diffuser.
- If you have any tubing exposed over land then you may want to dig a
trench and bury it to protect others from tripping over it or to
protect from being cut by lawnmower blades.
- If you did not purchase
the Deluxe version with the included compressor cabinet then you will
want to find proper housing or covering for your compressor, the
important thing is that the compressor is not directly exposed to rain
or snow as this can ruin your unit.
This is the basic instructions on how to properly install an aerator,
as you can see there is nothing especially difficult. If you ever have
