There are two ‘strengths’ of Ich-X
For Aquarium (Click): Water, Formaldehyde (<5%), Methanol (<2%), Malachite Green Chloride (<0.1%)
For Aquarium: To treat “ich” disease (ichthyophthiriasis) of freshwater fishes and “marine ich” disease (cryptocaryonaisis) of marine fishes, add one (1) teaspoon (~5 mL) of Ich-X® to 10 gallons (38L) of aquarium water.
For Pond (Click): Water, Formaldehyde (<22%), Methanol (<7.5%), Malachite Green Chloride (<0.2%).
For Pond: To treat “ich” disease (icthyophthiriasis) of pond and freshwater fishes, add one (1) teaspoonful (~5 mL) of Pond Solution® Ich-X® to 50 gallons (189 L) of Pond or aquarium water. One (1) ounce (29 mL) treats 300 gallons (1,135 L).
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® . 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.
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.
WARNING: DO NOT ALLOW TO FREEZE – If you find green crystals under the seal of the bottle when opening or noticeable clumps in the material when poured out, the product has been frozen and should not be used. When frozen the active ingredient can become lethal to fish. (Note from Doc Johnson: Formalin may form paraformaldehyde when frozen. Methanol attempts to protect against this but not always.)
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.
Use Ich-X® to treat conditions related to ich and ich related disease.
Dosage produces concentration of 0.5 mg/L of malachite green and 15 mg/L of formalia ~5.55 mg/L of Formaldehyde.
Note from Dr Johnson on Hikari Ich-X
The pond strength is perfect for dosing 1cc per 10 gallons of water to be treated. I would have no problem using pond strength in a fish tank but then, I’m extra careful. So that idea may not be for you.
Increase aeration but disconnect, stop or remove filtration media for the first 4-5 hours after application.
Treat daily x 3 days then every other day x 2 more treatments.
Water temperature should not be over 79 DF or dissolved oxygen complications may occur.
Water changes are “nice” after treatments to maintain good water quality. I like replacing water constantly via trickle systems.
