Why algae occur in aquarium
The causes of algae are unabsorbable excessive light, nourishment(nitrogen, phosphorus) from soil, carbon dioxide. A green algae is preliminary of plants evolution process, it has a lot in common with aquatic plants. Because required elements in plants growth are similar to aquatic plants, a lot of algae will be generated particularly in planted aquarium. From 10 days after setting up, algae will be visible to the naked eye and will be generated in 2 months intensively even in normal management. Generated algae not only take nourishment from surplus, but block out light to transmit to plants. It will have a really bad influence on plants growth.
