The pond in your garden must have been your favourite spot in your house. The fresh clear water, which is the home to lovely kois, never loses its charm. However, there are those days when the clear water becomes cloudy and show signs of imminent danger from algae. Pond keeping is a bit tricky and, of course, complicated. Sometimes even the seemingly healthy pond becomes plagued with algae, particularly during spring or summer season. Algae are not only to blame; oftentimes the verdict should point at the pond keepers inane activities and carelessness

Admit it or not, you are sometimes overwhelmed with pond keeping, unaware that you overdo things that may put your ponds life to risk. Overfeeding and overstocking fish can cause nitrates to accumulate in the pond and form green water. Failing to clean all unwanted debris in your pond may invite algae from invading your pond.

Pond keepers cannot monitor the pond from time to time, but theres one thing that will do the work. Pond filtration systems are must haves or most sought after garden pond supplies. Pond filtration system keeps the pond clean and healthy. There are various types of filters namely natural, biological and mechanical filtration all performs great role in maintaining the health of fish and the pond itself.

You have to consider adding filtration system if the pond contains lots of fish. Fish excrete waste which when break down produces nitrates and ammonia. These wastes should be rid off before they dilute in water and release toxic chemicals. The biological filtration is one of the most effective types of filtration system, particularly on smaller ponds. The bio filter may contain much dissolved oxygen and promotes better flow of water. And of course, the pond filtration systems effectiveness would not be enough without the mechanical filtration system that eradicate larger volumes of waste from the pond. The pre filter pump sorts the solid waste before it reaches the pump. It also contains good bacteria, but when used alone is not enough. There is also settlement tanks that are huge enough to house in wastes from the bottom of the pond.

Algae bloom may the hurdle the activity of the pond filtration system. Most experts claim that both biological and mechanical filters are defenceless against algae blooms. Biological filters provide little help, and are not enough to combat algae. Ultraviolet or UV clarifiers are the most effective treatment to eliminate algae, but they cant treat string algae or blue green algae. The UV clarifiers are available in different sizes to fit your pond, and are readily available in garden centres and retail outlets. How UV clarification works? The UV bulb kills the algae that pass through.
