Control fishpond algae. Different pond algae types

Pond algae appear as suspended minute blobs causing green pond water. Pond algae also attach themselves to all surfaces in the pond. The worst pond algae grow in long slimy clumps called string algae or blanket weed. Ponds will always have pond algae in one form or another. Dealing with them is important.

The good pond algae extends over all the sides and other fish pond surfaces. This type of pond algae grows to about 2 cm ( almost 1) in length. It becomes a haven for microscopic life on which the fish feed happily. It remains this length and is an asset in the pond. Do not try to remove this type of pond algae.

The not so good pond algae is the suspended kind. It is normally a green-coloured pond algae but may also be in shades of brown. The immediately obvious symptom is a fish pond looking like pea soup. This green pond algae is typically only 4 microns in diameter so that not even the best pond filters can remove it.

Do not let anyone tell you by the way that a biofilter or pond filters of any description are designed to prevent pond algae. A biofilter may help to reduce the incidence but does not prevent green pond algae forming. Even the very best koi pond keepers in the world install ultra violet light systems to prevent algae formation. They do not always like to admit it though.

Bad pond algae is known as blanketweed or string algae. It forms slimy long clumps which seem to grow at very fast rates ( hence the name string algae). This algae is normally associated with water that is otherwise crystal clear. This is because the string or blanketweed pond algae is so vigorous that other pond algae types cannot get a look in.

Blanketweed or string algae removal is notoriously difficult to achieve once you have it in your pond. The conditions leading to its formation are not well known. Even worse; there is no definite cure for this pond algae although there are many professed cures. These include barley straw and extracts from barley straw that certainly do show promise.

The big problem with "cures" for string algae in koi fish ponds is that they work some times and not others and the moment "stuff" to control string algae is put into a pond then a cycle of treatments to overcome side effects take place. Be careful of putting any treatment into your pond to remove your blanket algae problem.
