In obstinate cases full follow-up doses may be administered on the 3rd and, if necessary, on the 5th day after the initial treatment.
Cryptocarion: As for ichthyophthirius. Depending on the intensity of the infection, it may be necessary to continue treatment for up to 15 days.
Costia (Ichthyobodo): 1 outer capful for 10 litres of aquarium water 1 inner capful for 30 litres of aquarium water Treatment should be continued for a minimum of 7 days, with a full dose administered on the 1st, 3rd and 5th day. Raising the temperature to 30¡C is beneficial, providing that the fish can tolerate this tem- perature.
Note
If any other preparations (including plant fertilizers) have been used, two thirds of the water should be changed. Carbon filtering should not be used during treatment. Any UV water purifiers must be switched off. Also, any foam removers or ozonisers in saltwater must be switched off. Scaleless fish (loaches, silurids) or weakened fish may be sensitive to the medication. Begin with half the dose and increase carefully.
Approx. 50 % of the water should be changed immediately before each follow-up dosage.
