How could I lead an effective treatment with out destroying beneficial bacteria and consequently perturb nitrifying process?
Answer Dear Carlos, First let me apologize for responding so late. This was because our website has been under some reconstruction and as a result, pages take a horribly long time to load and many have errors. Certainly tail rot disease is bacterial in nature. It is uneccesary to go into the issues of what types and strains of bacteria they are right at this moment, but treatment should be fairly easy depending on the stages and levels of deterioration of the poor guppy’s fins. Early stages can be treated with a week long or more treatment of Melafix/Pimafix combination and plenty of daily 50% water changes always insuring the replacement water is equal in temperature to that of your aquarium and is dechlorinated. Further advanced cases may need stronger more potent medications such as Mardel’s Maracyn 1 or Maracyn II–both can be used together for a combined treatment. Water changes are still in order as always anytime your fish are ill. Very advanced cases of Fin rot can be difficult
