What is an aerator: There is no livewell system without a well functioning aerator that in the most simplistic description, pumps air into your tank. This aerator pump will push air through a hose and into the tank.
There are a wide variety of aerator systems on the market including:
New transom mount pumps that do not require thru hull installation
Oxegantor systems that minimize the amount of water needed for a livewell system
Replacement motor cartridge pumps that allow you to just replace the motor cartridge, similar to a bilge pump (and in many cases those motor cartridges are interchangeable between brands' bilge and aerator pumps)
Dual Port pumps are available for use with a second livewell, rinse hose or a high pressure washdown pump system with kits that include the aeration system and the washdown system
Some pumps have straight fittings and some angled and some with both
There are ice chest aerator kits that assist you in converting an ice chest into a livewell

Tips on Selecting a Livewell Pump (Courtesy of Rule Industries)
Always Select a pump that will deliver enough water to replace livewell water every 10 minutes.
Bigger is not better – too much pump capacity could lead to air locks
Mount the pump as low and close to the hull as possible
A Timer: Timers can be used to determine when and how much air you are feeding into your tank. Presetting these times will allow cycling and prevent over usage of your battery.
Water - Enough and the Right Temperature: Don't overstock your live well system. Recommendations are one pound of fish per gallon of water. Overstocking can cause the water to become rancid and kill your fish. Too little water for the number of fish in the tank can cause using up of the oxygen.
The water in the tank needs to remain cool (so watch those hot days) and be replenished with fresh at regular intervals. Pumping out the old and bringing in fresh helps keep the temperature at a moderate level and the water fresh for your fish.
Why a dual port aerator?
Dual port aerators offer the advantage of utilizing several applications through a single thru-hull fitting, i.e. the aerator pump.
With a dual port you can feed two livewells or use one for low pressure rinse hose.
You can also route one of the outlets to a positive displacement pump , using it for an intake in a high-pressure wash down application.
