A pond of stagnant water is a breeding ground for bacteria, pests, and other unwanted creatures. The contamination of water in your pond can result in illnesses, or worse, death of your fishes. That is why it is essential that you equip your pond with a piece of equipment that can promote the circulation of water and air inside your pond. This equipment is no other than a pond aerator.
A pond aerator is a must have for pond owners only because it can maintain the oxygen levels in the water and ensure the safety of the fishes living in it. But if there is one complaint that pond owners have with the use of a pond aerator is it consumes a great deal of electricity which in turn, costs them a lot.
This is the reason why solar pond aerators have been invented. These aeration kits come with solar panels that transform sunlight into electrical energy to power the aeration system. Since you will not be using electricity, this option can help you save money.
If you are planning on switching to solar power, you may want to take a look at this jam-packed and straightforward buying guide.
Why Do I Need Solar Powered Aerators for My Pond?
Most pond owners incorporate waterfalls and fountains in their ponds for aesthetic purposes. But while this equipment makes the pond more beautiful and pleasing to the eye, you should understand the fact that these equipment agitate the surface of the water. This may result in the dissolution of high oxygen levels in the pond.
The more oxygen is dissolved in the water surface, the lesser oxygen your fishes will receive. A pond aerator is usually installed to make sure that your fishes will get the level of oxygen that they need.
How do Pond Aerators Work?
If you have waterfalls and fountains in your pond, the best way to boost the oxygen levels in the pond is to pump air into its bottom part. That is what a pond aerator does. A Pond aerator kit is comprised of two items—an air diffuser and air pump.
The air pump delivers compressed air through an airline and then into the diffuser (which is located at the bottom part of the pond). The diffuser will then release the air bubbles into the pond. Once released, the air bubbles will rise to the surface of the water. This will result in the development of a slight current.
This current pulls down the oxygen-depleted water at the bottom of the pond then aerate it and brings it back to the water surface. Additionally, the air bubbles create boiling motion, which promotes the circulation of oxygen in the water and drives off unwanted oxygen like carbon dioxide and hydrogen sulfide.
How do Solar Aerators Work?
Most aerators are powered by electricity, but these days, you can find solar aerators for ponds. These aerators are equipped with a piece of equipment called a solar photovoltaic system. This system converts the energy that is harnessed from the sun into electrical energy, which then runs the pond pump.
It uses the same technology being used by other solar-powered equipment.
How Long Does a Solar Pond Aerator Last?
Since this is a relatively new invention, a lot of people think that this type of aerator is bot durable or long-lasting. Well, the truth is the total opposite.
Solar pond aerators are as durable as the electrical-powered ones. When you use this equipment regularly, it can last for up to 10 years. If you plan on using it casually, it may last for up to 15 years.
How Long Should I Run my Pond Aerator?
Most pond experts claim that pond owners should run your aerators 24/7. This is a must to make sure that your fishes will get the oxygen levels that they need. You see, getting low levels of oxygen regularly can stress the fish and weaken their immune system. As a result, your fishes have an increased tendency to get sick.
What are the Limitations of a Solar-Powered Aerator?
If you plan to abide by the tip mentioned above (running your aerator 24/7), you should understand the fact that a solar-powered aerator comes with a few limitations.
For one, the function of a solar-powered aerator is purely dependent on the sun. Because of this, there will be times when it will have a limited system runtime. This may occur during cloudy days or at night time when the sun is nowhere to be found. During those times when the sunlight is only 20%, the solar aerator cannot be able to harness enough sunlight to power the entire machine. As a result, it may only be able to run for up to 16 hours per day.
What are the Benefits of a Solar Aerator?
We already know the benefits of using a pond aerator. We are already aware of the fact that it can improve the water quality in the pond. But why should you go for a solar pond aerator when you have other more convenient option like a battery- or electrical-powered one?
A solar aerator offers two significant benefits that you cannot get from all the other types of aerators. For one, it can help you save on electrical resources. As mentioned, this type of aerator does not require electrical power. It allows you to take advantage of the already available source of energy—the sunlight. Because of this, you can minimize your use of environmental resources.
Last but not least, the use of solar aerator can help you save money. Since it does not run on electricity, you no longer have to fork out huge amounts of money to pay your electrical provider. Also, you no longer have to buy electrical cables that will run from the source to the pond.
What are the Factors to Consider When Choosing Solar Powered Pond Aerators?
If you have decided to invest in a pond aerator, there are lots of things that you need to consider to determine which product would best suit your needs. Here are some of them:
Under this category, there are two options that you can choose from. These are as follows:
– Solar-pump kit
This kit comes with a small pump which is placed at the bottom part of the pond. This pumps oxygen into the water, preventing stagnation and promoting good water quality. With the size of its pump, this kit is recommended only for small ponds.
– Floating Aerator
From its name, this aerator is placed on the surface of the water. It sprays oxygen into the water. It also helps to remove carbon dioxide and ammonia with the use of a stone diffuser.
Aside from aerating your pond, this can also act as an added decoration to your pond.
Before you invest in a solar aerator, it is highly recommended that you take a look at the product’s capacity first. This is a must to ensure that the aerator can deliver the right amount of oxygen levels to your pond.
To know if the aerator suits your pond’s needs, you need to check its GPH. This pertains to the number of gallons that the aerator can treat every hour.
If you have a large pond that contains up to 2000 gallons of water, a 300 GPH pond aerator is recommended for you. Using anything lower than that is not a good idea.
Where do you plan to put the aerator? Please keep in mind that the equipment needs to be exposed to enough sunlight to work. Because of this, it is recommended that you find an excellent location for it.
When looking at the location of the equipment, you also need to consider its size. You need to make sure that there is enough space in your pond for the aerator.
If you live in a place where sunlight is scarce, it may not be a good idea to use a solar-powered aerator. You may want to consider your other conventional alternatives.
• Panel sizes
It is the panel that absorbs and converts the sunlight. The larger the solar panel, the more sunlight it can absorb and convert. As a result, larger solar panels are able to emit and create higher amounts of electrical energy. It can, therefore, operate a more powerful and efficient aerator.
If you have a large pond, go for an aerator with a large solar panel. For small ponds, smaller solar panels will do.
• Battery Size
Same with the size of the solar panels, the size of the battery matters too. The battery of the solar panel will determine how well the machine will work even during low light conditions.
It is recommended that you check out the battery run time of the aerator. A good aerator should last for up to 4 hours at full charge under sufficient sunlight.
• Backup Battery
In addition to the battery size, you may also want to go for a pond aerator that comes with a backup battery. Keep in mind that the availability of sunlight limits the function of a solar-powered aerator.
If you want to use your aerator 24/7, having a backup battery is recommended. During the hours where sunlight is abundant, this additional battery can be recharged. You can then turn it on come night time so that your aerator will still have enough power to function efficiently.
• Water Flow
The power of an aerator determines the amount of water flow that it can create. To resolve this, you need to look at the wattage of the aerator.
