The peat extracts sold in the trade have the same beneficial properties on water as peat.
Peat is an organic soil type formed mainly from decaying plant material. It is mainly found in swampy or humid areas, where the decomposition of plant matter is slowed down due to the absence of oxygen. Peat can be used as a substrate in aquariums to plant aquatic plants.
There are several types of peat, including sphagnum peat, heather peat and pine peat. Each of these types of peat has its own characteristics and is used for different types of plants and situations.
Sphaigne peat is a sparkling and spongy peat which is very popular for its use in aquariums. It is easy to work and is ideal for fine root plants. It also retains water well and is ideal for maintaining the humidity of plants.
Bruyère peat is a denser peat and drier than sphagnum peat. It is ideal for thicker root plants and is often used as a substrate for flower plants in outdoor gardens. It also has water absorption properties similar to those of sphagnum peat, but it is generally less humid.
Pine peat is a lighter and more aerial peat than other types of peat. It is often used as a substrate for flower plants and climbing plants in outdoor gardens. It is also used as a substrate in aquariums, but it must be used with caution because it can easily disintegrate and obstruct the aquarium filters.
Using peat as a substrate in an aquarium, it is important to remember that it must be well rinsed before being used to eliminate any excess of tannins and other chemicals that could be present. The peat must also be changed regularly to avoid build-up of waste and chemicals which can be harmful to fish and plants.
