sera guide - Healthy pond fish

57 Important All sera treatments have been carefully checked considering their efficacy against the corresponding pathogens and their safety for users, the kept animals and the environment before they were ready for marketing. As a pharmaceutical manu- facturer, sera is subject to regular observa- tion by the authorities in charge. The close cooperation with successful breeders and retailers as well as the valuable feedback from our customers allows us to recognize possible problems or desires at any time and immediately react in an appropriate way. Our cooperation with scientists from different universities, plus of course the quality control and research activities of the highly qualified sera laboratory team ensures highest safety standards and new developments according to the current state in science and technology. Tip – Quarantine tank Some diseases should be treated in a qua- rantine tank. This in particular applies if only a few animals are infected and you wish to avoid infecting the other fish, or if applying a treatment in the large volume of the pond is not practicable, e.g. due to required partial water changes. Necessity to raise the temperature may be another important reason for treating in a quaran- tine tank – this especially applies for virus infections. If in need you can even use a bucket with an airstone (sera air plus air pump) as a quarantine tank if you have to treat only for a short time and the fish are not too big. A larger tank with good aeration and a heater is of course better. The water you use should have the same temperature and the same pH value (also check other values if required) as the pond water. A filter is not necessarily required if you keep the fish in the tank only for a couple of days. However, in that case it is very important that you change the water more frequently. For instance, you should carry out a partial water change every other day when using sera baktopur direct as to maintain optimal water quality. The water temperature is slowly raised (sera aquarium heater thermostat) after adding the fish, if required (especially in case of virus diseases). Please be aware that the cured fish must not simply be put back into a cold pond from a heated quar- antine tank. The temperature difference might lead to a relapse or to other diseases in the weakened animals. You can lower the temperature of the quarantine tank very slowly [by not more than 1°C (1.8°F) per day] again and put the fish back into the pond after an appropriate adaptation phase under observation. You can alternatively also wait until pond temperatures have sufficiently risen in case you carried out the treatment in spring. When treating in quaran- tine during winter it may be necessary to keep the fish in the separate tank until spring. 10 General recommendations for application !! !!
