Water Treatments
Pond water often needs special treatments in order to stay clean, clear and healthy. Murky water can be caused by nitrogen in the surrounding soil and also if the pond fish are over eating foods that are high in nitrogen and creating excess waste. Adding composts or fertilizers to soils that are in close contact with the pond should be avoided as should over-feeding the pond fish. Also dirty or cloudy water can be caused by debris in the water and /or excessive amounts of algae in the water. This can be cleared up by protecting the water from algae growth using biological filters and bacteria and by removing debris and waste from the pond water.
Green pond water and blanket weed can occur in new ponds when most of the water has come from a tap, has high Ph levels and is high in nutrients like phosphates and nitrates. Biological filters can be used to prevent blanket weed and UV filters are often used against green water. Covering the ponds with nets and clearing the debris reduces the nitrogen content of the water as it reduces the amount of waste decaying in the water.
