sera guide - Healthy aquarium fish

Partial water changes and removing treatment re- mainders through active carbon (sera super car- bon) are in most cases re- quired. Please observe these measures exactly as well. A considerably longer treatment applica- tion time caused by not carrying out these meas- ures does not improve ef- ficacy but – on the con- trary – may lead to undesirable side effects. Some treatment agents can have harmful ef- fects if applied for a longer time. Other treat- ments contain solvents that are broken down by bacteria as nutrients, which increases the risk of a bacterial bloom. In case of large water changes being required (e.g. at least 80% for the sera med Professional products) it is pos- sible to proceed stepwise: e.g. several 30% water changes within one or two days. This re- duces the stress for you and your fish, espe- cially in case of large fish, using reverse osmo- sis (R/O) water, etc. The water should by all means be conditioned with sera aquatan or sera blackwater aquatan when conducting a water change – among others, this will bind re- maining treatment remainders. You can quickly Vitamins 10 General recommendations for application Using vitamin preparations is another excep- tion. It is also safe and recommendable in combination with treatments. Just as in hu- mans, vitamins fulfill many vital functions within the fish organism. They are, among others, re- quired for a strong, active immune system. The own disease resistance – provided it is opti- mally functioning – is the best possible protec- tion against diseases an organism can have. If you feed your fish high quality sera food, you already ensure, good basic supply with vita- mins and all other important nutrients. Please be aware that the included vitamins may in- creasingly be broken down by the effects of at- mospheric oxygen, light and moisture. It is therefore ideal to choose food cans that you can consume within several weeks to a few months. You should additionally support the immune system with an extra vitamin supply in stress situations (e.g. fish transfers, courtship, brood care, temperature changes) or if pathogens got into the aquarium. Use sera fishtamin in such situations. You can add the preparation directly to the water according to the information for use or soak the food with it just before feeding. The sera FD foods are partic- ularly well suited for this pur- pose. Regular addition (once or twice weekly) or using the vitamin drops as a treatment (once daily) for several weeks are both possible. Such treat- ments are advisable in the mentioned stress situations and during a disease. Contin- ue the treatment for at least a week after the disease symp- toms have vanished as to sup- port recovery and minimize the risk of a relapse. Concluding the treatment 62
