To treat “ich” disease (ichthyophthiriasis) of freshwater fishes and “marine ich” disease (cryptocaryonaisis) of marine fishes, add 3 drops of Quick Ich-X® per 2 gallons (7.5L) of aquarium water.
For Best Results: (1) always treat in a separate quarantine/treatment tank, (2) remove activated carbon from filters and clean or replace mechanical filtration media (do not stop filtration!) (3) make at least 1/3 water change before each addition of Ich-X® (use Ultimate® or a combination of Stress-X® and ClorAm-X® to condition new water). Larger water change improves performance; and (4) repeat treatments at least every 24 hours, but no more than every 8 hours, depending upon the course of the disease (refer to the Ich-X® Product Data Sheets for Aquarium or Ich-X® Product Data Sheets for Pond). Continue uninterrupted treatments for three (3) days after all visible signs of disease conditions cease.
DO NOT OVERDOSE - this means you should calculate the actual amount of water in your tank by multiplying the length x width x height and dividing by 238 to get the true gallons. Please also deduct the amount of space consumed by substrate (gravel, sand, etc.) rock, decorations or other things which are displacing water.
NOTE: We do not recommend using any sulfur or sulfinite-based water conditioners with this product. If your normal water conditioner does not list the ingredients please verify with the maker that it does not contain these ingredients. If you notice any rotten egg smell to the product, it likely does have these ingredients and should be avoided as it could cause the product to be less effective and the dissolved oxygen levels to be negatively impacted.
