It's a mix of formalin and malaclite green. Save your money, It only works on the free swimming stage
Only true way to get rid of ich is QT everything with either copper or chloroquine phosphate and allow tank to go fallow for minimum of 6 weeks
of the diseased fishes). Treatment should be repeated no less than every 24 hours (see step c) and continued for at least 3 days beyond the disappearance of all signs of disease. The main problem is in knowing when all white spots are gone from inside the mouth, gills, and nostrils of the fish. Typical treatments for Ich will depend upon the species of Ich involved, and may require six to 35 days or more in daily treatments. This means that daily partial water changes will need to be made followed by daily re-dosing of Rid-Ich+ until the infection is entirely gone. There are a number of "Ich" white spot species that can be involved, each with a different length of time of its life cycle in the white spot stage. In general these different species have different white spot stages varying from about 3 days as dormant white spots, to one week, to two weeks, to three weeks, and to 32-35 days or more. It takes an expert with microscopic examination to determine which species is involved. They all look alike. During the white spot stage the Ich are not treatable by any known treatment. Only when the Ich are hatched from the white spots and free swimming are they able to be killed by a treatment.The actual time necessary will depend upon the particular infection, the degree to which the fish are affected, how early the disease is detected, and when appropriate treatment is started. Note: Failure to properly diagnose a given disease and failure to start appropriate treatment early enough will often result in the death of some or all of the diseased fishes.
