Types of Algae

Algae what are they?

About three billion years ago, the algae were the first plants that developed. These are the oldest known organisms, which contain the color chlorophyll (leaf green, see the terms). The photosynthesis process, made using light nutrients, is one of the most beautiful processes in nature.

The appearance of algae was closely linked to the build-up of oxygen in the atmosphere that caused the ozone layer, which caused the fatal ultraviolet rays to open up the possibility of life forms to settle in surface water. Algae have been the only plants in the world for 2.5 billion years. Only 500 million years ago were the higher plants. During their endless long life, algae have provided an ecological performance for further development of flora and fauna on earth.

Float algae

Also called water flow. After a while, the water turns opaque green.

Blue algae

Blue algae usually begin to grow on the bottom to cover the whole bottom with a slimy layer. Blue-green, more or less solid layer, which mainly covers the plants. Generally forms silvery shiny oxygen bubbles and, when taken from the water, spreads a bad smell. Blue algae are sensitive to low concentrations of hydrogen peroxide.


Combating blue algae seems successful. Researchers seem to be able to tackle the blue algae. Wageningen University, engineering firm Arcadis and the University of Amsterdam used hydrogen peroxide. The blue algae is a bacterium that secretes a toxic substance to humans and animals: microcystine. At a low amount, that does not matter, but at larger amounts. Headache, fever, diarrhea and eye irritation are the consequences.

The hydrogen peroxide cure is the only cure that, if done well, kills only the blue algae. For this you use hydrogen peroxide 3%. Hydrogen peroxide appears to be an efficient method of combating blue algae in surface water. Addition of hydrogen peroxide may work but never be overdosed. Prevention is better than cure. But the words of Thomas Barr seem correct. The use of hydrogen peroxide may be a move in the right direction. But it’s not the perfect solution. The Bio-Guard drug works well against the blue algae.

Brown algae

Brown, often slimy layer on all objects in the water, especially on the leaves of slowly growing plants.

Red algae

This is a whole group of algae, which according to the type and appearance of the hobbyist or Beard, brush and brush algae. They are so unpleasant in the aquarium because they are hard to remove.

Short, 2 – 15 mm green hairs, covering walls, stones and slowly growing plants and often so stuck that they can hardly be removed.

1 to 50 cm long wires swinging through the tray

Green algae / Beard – or mustard algae

This name is actually a collective name for various types of green algae. The green algae have an agreement, they all have chlorophyll. They are even a sign that water relations are alright. They are well recognizable by their (light) green threads or cotton-like spins.

Algae removal

The oldest known method of combating is based on plant competition and limiting organic taxes.

All life on earth consists for the most part of these organic substances.

A major problem with water artificial turf fields is algal growth. Water artificial turf fields, unlike sand, are artificial turf fields. Due to these dense constructions, the water is kept regulated, so it does not matter, and in such a field it can technically be very good hockey. Problem: “On the top layer of such a field, dirt often occurs through footwear, but also pollutants from the sky (leaves, bird cloak, etc.) are on the field. Combined with the ‘warm’ artificial turf, water and especially light, a perfect base for growing algae on the synthetic turf fibers is created. The result is that the soil is contaminated, densified and especially smooth. “Cyanobacteria (also known as algae) bind together with other bacteria to the synthetic grass fibers: this results in a so-called biofilm that makes the grass mat smooth and which can cause clogging . “This can be prevented by adding a quaternary ammonium compound to the spray water, the agent Bio-Guard. This drug stagnates the growth of algae.

Several hockey clubs have gained experience with this procedure, spraying 1x a week a night. Why at night? Spraying at night keeps the product longer effective and the influence is greater. The quaternary ammonium compounds of the Bio-Guard agent act less like hydrogen peroxide less under the influence of light. Algen Control has these experiences from the agricultural world in which Mr. Overwater has been active for many years.
