Fittings for an Aeration System
There are several pond aeration systems you can buy in order to avoid your pond becoming over grown with algae due to the water having inadequate oxygen. These systems are usually divided into two categories; those suitable for ponds with a depth of 6 feet or less and those with a depth which is more than 6 feet. Obviously as there are different systems available, the pond aeration fittings also differ but most will need a power source of one kind or another. Most aeration systems will work with mains power but as some ponds are located far from a mains outlet, some come with their own source of power. Some systems come with a windmill kit and once set up; the turning of the windmill will provide enough power to operate that particular aeration system it came with. Other aeration systems use the power of the sun as they come complete with a solar energy kit. Obviously these solar kits need sunlight in order to provide power but some of them are able to allow the aeration system to work for 3 days without seeing any sunlight. Although these individual power sources are intended for use where ponds are far from a mains outlet, they can still be used by people that do not want their mains bill to increase. Fountains can be very pretty and are often used to enhance the beauty of a pond but a fountain is also an efficient aeration system for a shallow pond. The fountain creates circulation in the water of the pond which in turn allows for different water to be thrown up by the water. As the water is thrown into the air, it has the opportunity to react with the air and extract the oxygen it needs to remain healthy. Perhaps not providing the elegance that a fountain can, a propeller aeration system is also as efficient as a fountain when it comes to the aeration of a pond. With this system the propellers churn up the water at the surface of the pond, allowing it to come into contact with air and as the propellers also create a circulation, they also allow all the water in the pond to become aerated.
When a pond does not have aeration, it will slowly become unhealthy with the fish first dying and then the algae which thrive on un-oxygenated water at the bottom of bodies of stagnant water, then taking over the whole pond. Not only do these algae look unsightly but it also produces an odour which most people find unpleasant. As algae start to grow at the bottom of ponds, it is important to use a diffusion aeration system for the deeper ponds. With one of these systems, a compressor pushes air to a diffusion unit located at the bottom of the pond. Air passes from the compressor through a hose to the diffusion unit where it is allowed to escape into the water at the bottom of the pond, aerating it and it continues to aerate the water all the way to the surface.
