About This Item

Details

  • Dual-strength formula controls Ich and other external protozoan, dinoflagellate and fungal diseases of freshwater or marine fish.
  • Combines formalin and zinc-free chloride salt of malachite green for higher efficiency so you can use less, and is safe for fish sensitive to malachite green alone.
  • Won’t interfere with biological filtration systems so it helps keep your aquarium or pond water clean.
  • Great for treating fungal infections, white spot disease, Ichthyophthiriasis, Costia, Trichodina, Chilodonella and saltwater external parasites such as Cryptocaryon and Amyloodinium.
  • Made in the USA and is easy to use, and totally safe and non-toxic to fish in aquariums and ponds.

Kordon Rid Ich Plus, the instructions say to use once every 24 hours, but it does not say for how many days or weeks to use it for. How many days or weeks should we use it?

Answer by ChewySep 03, 2020
Treatments may be repeated as often as every 6-12 hours (depending upon the severity of the particular disease and the tolerance of the diseased fishes). Treatment should be repeated no less than every 24 hours 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.

can this be safely be used around snails?

Answer by ChewyMay 24, 2019
It's not recommended to use this product around snails. However, Kordon Prevent Ich Natural Ich Disease Aquarium Inhibitor can used around aquatic invertebrates (such as snails, crustaceans, corals and sea anemones).
