Even less studied is the life in the oceans, which often make sensational discoveries.

The existence in the seas and oceans are dangerous animals the people knew even in ancient times, although along with very real views were widespread tales of fantastic sea monsters.

Preparing the pond for winter

You have built a pond, planted it with plants and settled there living inhabitants. All summer did observe a small world, with interest to discover something new… autumn has Come. Now we need to think about how to save water world in winter. Well, if the weather isn’t frosty, but if not? All you need to provide.

Prepare ponds for winter starts in the fall, in October. First of all, you need to thoroughly clean the ponds from organic debris (tree leaves, remains of plants, fish excrement, etc.). In winter because of low temperatures reduce the activity of bacteria that decompose these residues. The result is the siltation of the bottom, reduces the oxygen content in the water and increases the content of nitrites and ammonia. Naturally, such changes can adversely affect the inhabitants of the lake, if not to destroy them. After cleaning of organic residues, it is necessary to trim the leaves and shoots to the very root. This applies primarily to plants – oxygenators. These include the water Crowfoot, hornwort, bolotnitsa, twrch, canadian Urrutia, lagarosiphon, tilea, rest and others. The leaves of these plants die off for the winter and if they advance not removed, they will rot and pollute the water. Not only cut the cane, through the hollow stems in winter will be given carbon dioxide to enter and oxygen to simulsays and plants.

Many aquatic plants “invented” a way to survive the winter cold. In autumn they formed buds that sink to the bottom and “sleep” there in the spring. If the pond is artificial, it is desirable to cut the plants these buds and transfer them to winter indoors. This stored the buds in the spring will sprout and turn into new plants. And do it faster than if left to overwinter in the pond. Continue reading
