How to Choose The Best Pond Aerator
Importance of pond aeration
Pond aeration is very important for both your pond’s health and looks. It is particularly important if you keep fish in your pond.
The first important reason to aerate your pond is that oxygen is required by the beneficial bacteria that will decompose the plant matter that falls to the bottom of the pond. Without it, you will end up with lots of dirt and debris such as decaying plant matter and fish waste forming at the bottom of your pond and rotting creating a stagnant and unhealthy pond.
The second important benefit of pond aeration is to stop an effect known as layering in your pond. This is when the pond water splits into different layers depending on the temperature and oxygen level. If a pond layers, only the top portion of the pond will have adequate oxygen for your fish. This can mean there is not enough space for your fish in your pond as they can only use a small portion of it.
The other danger of layering is when the top becomes oxygen-rich it becomes heavier than the water below it. This can cause it to sink and mix all the pond water. This will then rapidly drop the entire temperature of the pond but also make oxygen to scarce for fish. This puts all the fish in your pond at very high risk as they will be too cold and not have enough oxygen.
Using an aerator for your pond is very important for the health of your pond inhabitants from the beneficial bacteria to the plant life and, of course, the fish.
Flow rate is the measurement of how many litres the pump can move. This is normally referred to as LP/H standing for litres per hour. Larger ponds will require more water to be moved to properly aerate the pond effectively, so the larger the pond the higher the LP/H you will need.
Having an energy-efficient pond aerator will save you money on your electricity bill. It can be hard to determine the energy efficiency. Some products will use the standard efficiency rating similar to your typical electrics like washing machines, this gives them a letter rating from A+ to D.
Alternatively, you can roughly work out how efficient it is by comparing the watts used to the LP/h. if you have a pond aerator that uses low watts say 5 watts and still creates an LP/H of 400 this is going to be a good energy-efficient option.
Having a good reliable pond aerator is important as it ensures a healthy pond. Obviously, it is also a hassle if your aerator breaks down. All of the products on our list provide a reliable option and include replaceable parts to improve the longevity of your aerator.
Weatherproofing allows you to leave the pond aerator outside without having to worry about frost and rain. If you have a non-weatherproof option, you will need to store it in an outside building such as a shed and then run the plumping outside to the pond. If you don’t have an outside room near your pond or don’t want to run plumbing through it then a weatherproofed option is a must. Otherwise, it will not withstand rain frost or even splashes from the pond.
Pond aerators are a very important tool to keep your pond happy and healthy. The appearance and health or your pond and its inhabitants will be improved by good aeration. I would recommend the Oase AquaOxy 1000 Pond Aerator as the best pond aerator thanks to its powerful, quiet motor and excellent weatherproofing.
