Livewells come complete with livewell, pump and air control
valve, and battery clips. They are available in 10, 20 and
30 gallons.

KeepAlive Oxygen Infusors .........
NEW! from the USA
KeepAlive pumps are 12 volt, high performance
salt and fresh water livewell aerators, that KeepAlive
more catch and bait in a smaller amount of water.
They are Guaranteed to outperform
all others in their category!!
This new process is the only one of its kind
in which air is chopped by the pump into millions of very
fine life giving air bubbles. This produces more than enough
air to keep your catch alive but gentle enough for the most
delicate bait.
The units are available in two sizes, the KA460 suitable
for live bait wells up to 20 gallons, and the KA1100 suitable
for 30-40 gallon bait wells (shown). The infusors come complete
with pump, air supply hose, air control centre, battery terminals
and instruction booklet. All units are supplied with 6 feet
of cable. The KA460F floating version of the KA460 is suitable
for prawns.

Understanding the concepts
of aeration.
There are many misconceived ideas about aeration.
Two common fallacies are:
Large live wells are required to sustain a large quantity
of fish.
Large live well pumps are needed to move large quantities
of water through the live well to keep live bait and fish
alive.
To understand what is really needed in proper aeration, it
is best to take a look at ourselves.
FACTS
If we were enclosed in a large airtight room we would
be able to breathe for many hours before we would consume
all the oxygen.
If we were in an airtight closet, the oxygen would be consumed
a lot quicker.
If we were swimming underwater without a snorkel, the oxygen
in our lungs would be gone very quickly.
In all cases, without additional oxygen we would expire!
However, we could stay alive indefinitely, if we could
use a breathing tube or snorkel that was in contact with outside
fresh air or oxygen. It would not matter about the size of
the container that enclosed us.
An aerator is to a fish, what a snorkel is to us!
The smaller the air bubble, the more slowly it will rise,
giving it more time to dissolve in the water.
Due to the higher density of salt water, air bubbles are usually
smaller in salt water than in fresh water.
A large 20mm bubble has a volume of 4.19 cm3, and a surface
area of 12.6 cmsq
You could make 260 small 3mm bubbles from the large bubble.
They would have a total surface area of 83.6 cm2. This is
6.6 times the surface of the 20mm bubble.
The small bubbles, can theoretically aerate 6.6 times as much
water with the same amount of air.
Knowing the importance of air bubble size, the effectiveness
of different aerator systems becomes readily apparent!
