toxic substances always present in tap water – chlorine, chloramines, and heavy metals. Its use helps fish cope with stress caused by transportation, relocation, or sudden changes in hydrochemical parameters. Micro-injuries in fish heal quickly, gill respiration and osmotic pressure are optimized, and the protective mucous layer on the body is restored. It is used when preparing water for a new aquarium and when replacing large amounts of water in old aquariums. It is used as an auxiliary agent in the treatment of sick and injured fish. It is essential during the transportation and transfer of fish. Dosage: As an auxiliary agent in the treatment of scale and fin damage – 2 teaspoons (10 ml) per 38 liters of water. To remove chlorine – 1 teaspoon (5 ml) per 38 liters of water. The bottle is enough for 227 liters of water.

Tropical biodesinal. This is a solution containing active iodine for the effective control of many microorganisms that cause diseases in fish. Prevents the growth of 
fungal infections in the form of cotton-like plaque, as well as other diseases affecting the skin or other areas where the mucous membrane has been damaged. It can also be used as prophylactic baths for newly acquired fish and plants.
Diprovan. Has an antiparasitic effect against fish ectoparasites localized on the integumentary tissues of the body, gills, oral and gill cavities, and fins, 
including Costia, Chilodonella, Trichodina, Oodinium, gill Cryptobia, Apiosoma, Brooklynella, Heteropolaria, Tetrahymena, Uronema, Trichophrya, Gyrodactylus, and Dactylogyrus. It is used for prophylactic antiparasitic treatment of newly acquired fish. It dramatically increases the intracellular osmotic pressure of parasites, depriving them of the ability to hold onto the fish’s integumentary tissues. The resulting anxiety and movement coordination disorders pass quickly. It is used for invasive diseases of ornamental fish in the form of dip solutions: for prophylactic purposes against freshwater fish parasites, once; for therapeutic purposes in gill cryptobiosis, oodiniosis, dactylogyrosis, gyrodactylosis, and saprolegniasis of freshwater and marine fish – 3-5 times. Prophylactic treatments are carried out before introducing newly acquired fish into the general aquarium, during fish transfers, using a dip solution of Diprovan at a concentration of 6.1 g of the drug per 0.5 liters of water.
To treat fish, catch them with a cotton net in batches of 10-20 individuals (total weight not exceeding 50 g) and submerge them in the net into the dip solution for 5 minutes. Then the net with fish is removed, rinsed thoroughly in a basin of settled water, and the fish are released into the aquarium. One dose is dissolved in 0.5 liters of water. 10-20 fish are placed in a deep net and lowered into the solution for 5 minutes. Then the net is transferred to a vessel with clean water, rinsed, and the fish are released into the aquarium. The solution can be used for 4 hours to treat 4 batches of 10-20 fish each.
