Empty 1 capsule into aquarium for every 20 gallons of water. Begin treatment with mew water and do note stop filtration. Remove activated carbon and UV sterilization to ensure effectiveness. Distribute the contents around the edges of the environment or directly into the filter box for the best overall distrubtion. Do not apply more than once every 3 to 5 days. One treatment of 5 to 7 days is generally sufficient. Fish Tapes Forte may be used as a preventative when used only at the standard treatment. Do not use with any other drugs. Use in saltwater systems where flatworms of the Polycladida order are being cultivated is not recommended as some contradictions will apply.
