A week ago, the water in the pond was completely transparent, clearly visible at the bottom of the stones and scurrying between the small fry.
And in the current your arrival entire surface turned green. "Water blossom" - say in such cases.
Causes of algal blooms
There is in Russia asusually in late July - early August. Flowering water in the pond is caused by an excess of nutrients, especially phosphorus. High concentrations of phosphates causes excessive growth and reproduction of the smallest single-celled algae. Moving green and blue-green algae (group Volvocineae and Cyanophyceae) stained water in a bright or dark-green, yellow-green and blue-green color. A group of algae Porphyridium cruentum Naegeli can give water an eerie blood-red color. However, this happens with a few rain puddles - in larger bodies of water, this pigment is hard to discern.
Flowering water is usually characteristic of freshwaterwater bodies - lakes, oxbows, filled with large ditches, and pools, where the water is stagnant. Sometimes the phenomenon of algal blooms observed in the bays and coves with salted water.
The longer and more intense, the process offlowering water in the reservoir is less dissolved oxygen. This often leads to the formation of Zamora zones where aquatic insects and many fish begin to die en masse. In addition, neurotoxins, which in the process gidrotsenoza produce some types of algae are poison, and in large quantities pose a serious threat to the wildlife pond.
Flowering water in the aquarium
If you put a jar with ordinary tapwater on window, well illuminated by the sun during the day, then a 1.5 - 2 weeks water in it turns green. In the aquarium, in addition to the fish and other inhabitants placed in it, there are microorganisms and beneficial bacteria, which are involved in the process of biological equilibrium. They hinder the development of putrefactive bacteria, recycling uneaten food and fish allocation. Despite this, if you do not interfere with the natural biological process, the water in the aquarium also bloom. And this can happen and the middle of winter. The causes algal blooms in the aquarium can be an excess of light exposure and overfeeding inhabitants, causing the bacteria do not have time to recycle leftover food. The consequences affect the well-being of fish and other inhabitants.
In order to prevent blooming, it is necessaryprodelyvat every 2 weeks to change 1/5 of the water volume in the fresh and collect deposits from putrid soil. And the bigger the tank, the less need to perform these procedures.
