Pests of the aquarium: how to deal with them?

In the aquarium these Microorganisms under certain conditions begin to multiply actively and interfere with the livelihoods of its inhabitants. To harmful organisms, first of all, the causative agents of fish diseases, most of the invertebrate animals that enter the aquarium, as well as the development of lower algae. Such algae - it's not those beautiful plants that are planted in the ground, these are small organisms that occur in all water bodies.

Many of them can be serious enemiesthe aquarium. They cover the leaves of plants, the bottom and walls of the aquarium, make it difficult to observe the aquarium and spoil its appearance. Algae harm plants, consume oxygen in the time necessary for fish, and some also release toxic substances into water and change the chemical composition of water. This can lead to the death of fish and plants.

In aquariums like to settle blue-green, brown, filamentous, unicellular and other algae. They must be regularly removed during the cleaning of the aquarium, cut off the leaves affected by them, and sometimes even the plants as a whole. Thrift here can only do harm.

Films and raids from algae are removed with a hose. With a strong development of algae, it is recommendedreduce or even temporarily stop feeding fish and change water several times, and it should be topped up from an aquarium with well-developing plants. It will be very useful to remove all dirt from the aquarium. These measures will reduce the mineral content in the water and leave the algae without food. Also You can increase the number of snails in your aquarium, which remove algae from the surfaces of glass, stones and appliances inside.

Karpoeid, fish louse, and scientifically "argus" - is also a very unpleasant phenomenon. These zhabrohvostye crustaceans feed on the blood of fish,parasitizing on their skin. They are quite large, about 4-8 mm in length and, most importantly, they have a translucent body, painted in a greenish-yellow or grayish-green color, which is why they are not clearly visible on the body of the fish. Parasites pierce the skin with a proboscis, this place becomes inflamed, swells and becomes open to various infections. To clear the aquarium from the argument, you need to leave the aquarium without fish and raise the temperature to 26 ° C, it is good to light and hold it for a week. Still it is possible to delete arguments from a body of a fish a forceps, but it is very difficult.

Hydra - an invertebrate animal - enters the aquarium withfodder or plants most often from natural reservoirs. Soya hydra attached to plants, to the ground, to the glass, its tentacles react to movement, capture and paralyze prey - crustaceans and fish fry. In the fight against the hydrate, you can use ammonium salts: sulfate (NH4) 2SO4, or NH4NO3 nitrate. Ammonium sulphate is added at a concentration of 50 mg / l, and nitrate - 80 mg / l. It is desirable to raise the water temperature to 28-34C. In such conditions, hydra die within 3-6 days. For fish, the addition of ammonium salts is practically harmless.

Another pest - planaria - a flat worm, which, getting into the aquarium withlive food, destroy caviar, larvae and fish fry. To get rid of the planaria, usually raise the temperature of water to 30-32 ° C, which can withstand many tropical fish. Chemical methods of controlling planarians suggest copper sulfate (1.5 mg per liter of water) and ammonium nitrate (25-50 mg per 1 liter of water with double treatment).
