Biological filters

Biological filter: The primary goal of this type of filter is non-toxic, organic pollutants and changes. Biological filters are usually two or more layers of gravel plug in large colonies of bacteria live, such as gravel or other materials contained. Water seeps slowly through bacteria, algae, harmful bacteria, ammonia and fish waste to nitrate variation. These nitrates are absorbed by plants of nutrients. All biological filters, which pass through them, there must be a continuous flow of water of oxygen in the water-living bacteria. Despite continuous biological filter is actually a mechanical filter, which requires less energy to go in a clean once a month.

Work, a lake, a waterfall or fountain is not yet finished installing, maintaining constant problem. Automatic water in the garden will be ugly and poisonous. Pay attention to the need, and beautiful, and be rewarded with a relaxing fountain.
