Green Point Algae

green pointed algae

Green pointed algae is a type of algae that often occurs as small dots on the windows, leaves and hardscape. A distinction is made between green pointed algae (GSA) that are very firmly attached to a surface or softer green pointed algae that are easy to wipe off. The easy-to-wipe variant is also called green matter algae (GDA).

The causes of green point algae

In this article we discuss the hard variant of the green pointed algae. The thin, green circles on hardscape and aquarium windows are often a result of excessive lighting and too many nutrients. Naturally, any presence of these algae in the aquarium is not immediately something to worry about. If this alga is also present on, for example, the leaves of Anubias or other aquarium plants, there is most likely a lack of phosphate. This can be determined with an aquarium test for phosphate (PO4).

Measures against green point algae

The green pointed algae that is present on the windows can easily be removed with, for example, a Razor . Check whether there is perhaps too much light or whether direct sunlight is entering the aquarium. Is the alga also present on stones or wood? Then an ADA Pro Brush or Pro Picker can offer a solution to remove the algae. Is the algae also on the plant leaves? Then try to see if the phosphate level is in order. Sometimes there is no other option to remove excessively infested leaves.
The use of algae-eating animals should also be considered. In particular, antler snails (Clithon sp.) and Runner snails (Neritina sp.) are there to "graze" the aquarium cleanly around streams.

By taking the above measures, the population will be reduced and green pointed algae will decrease in due course. A return decreases further with each service. Regular maintenance and "prevention is better than cure" will then keep the algae under control.



Do you have photos of pointed algae that we can use on this page? We are happy to receive them at our email address.
