About 90 % of all fish diseases can be put down to a weakening of the fish’s immune system. This means the application of remedies can fight the pathogen but doesn’t generally eliminate the cause. It is therefore very important to determine the cause.
As soon as the first signs of disease become noticeable IMMEDIATE action is required. In most cases people wait too long.
Internal and external bacterial infections can take on a wide variety of appearances, which can quickly and reliably be combated with JBL Ektol bac Plus 250 , JBL Furanol Plus 250 20T (not to be sold over the counter in Germany) or in the garden pond with JBL Ektol bac Pond Plus or JBL FuraPond (not to be sold over the counter in Germany). Whitish coatings often appear on the fish skin. However, bloodshot spots can also be discerned or completely different symptoms can occur. A clear diagnosis is only practically possible with a microscope.
We often assume it is a parasitic infection, choose a suitable medicine, such as JBL Punktol Plus 125 and if it doesn’t get better we use JBL Ektol bac Plus 250 or JBL Furanol Plus 250 20T to combat bacterial infections. See also Notes on JBL Ektol fluid Plus 125.
If a microscope is available, distinguishing between bacterial and parasitic diseases is relatively simple: Most parasites are already clearly recognisable as moving objects with a 100-(!)-fold magnification. By contrast, bacteria are so small that they cannot even be recognised clearly with a 500-fold magnification. To put it simply: If you see objects that are clearly visible and moving around, they are most likely parasites. Conversely, if you don't find anything, you are probably dealing with a bacterial infection.
