sera guide - Healthy aquarium fish

9.5 sera med Professional Argulol A safe and reliable treatment against parasitic crustaceans – and crus- taceans that serve as intermediate hosts – is now possible with the unique treatment sera med Professional Argulol (for freshwater and saltwater fish). This treatment is also excellently suited for a preventive treatment of animals and plants that possibly might carry such parasites. The crus- taceans (everywhere in the water and on the fish) will be gone after just one day. The treatment is broken down biologically, thus no remainders will re- main in the water. Water changes or filtering through active carbon are there- fore usually not necessary. However, a partial water change is recommended in small aquariums, as to maintain constantly unobjectionable water quality. Repeating the treatment after about three weeks is advisable as to kill the crustacean larvae that have hatched from eggs in the meantime as well. Please follow the application advice by all means, since the treatment is also not tolerated by some desired invertebrates (e.g. shrimps and crayfish). A quarantine treatment is therefore often favorable. The fish treated in the quarantine tank should first be transferred into non-treated water as to wash off the treatment remainders before they are put back into the main tank. This in particular applies for saltwater tanks with very sensitive invertebrate inhabitants. According to our observations, sera med Professional Argulol is tolerated by amphibians and plants without any problems. In case the treatment cannot take place in the main tank due to sensitive in- vertebrates, there is a certain risk that parasitic crustacean stages remain there and may infect the fish again when they are put back. This especially applies if the fish can be kept in the separate tank only briefly and the crus- taceans in the main tank that require a fish host have not yet died. Consis- tent hygienic measures, such as repeated water changes and carefully cleaning the decoration items, the plants and the bottom ground by intense siphoning, reduces the population of parasitic crustaceans until the finally disappear entirely. If required, strongly infected fish must be caught again and treated in a short-term bath. It may be necessary in some cases to conduct an aftertreatment for the wounds the crustacean parasites caused on the fish, as to avoid subsequent infections. Use sera ectopur in slight cases, sera med Professional Pro- tazol is recommended in case of more severe infections. 57 Professional
