API Super Ick Cure API Super Ick Cure targets ich (Ichthyophthirius), the white-spot parasite that's the single most common disease in the hobby — the telltale scatter of salt-grain white dots on fins and body, usually triggered by stress or a chill. It's a fast-acting treatment that kills the free-swimming stage of the parasite to break its life cycle and clear an outbreak before it overwhelms a tank. Good to Know: Ich has a temperature-driven life cycle, and medication can only kill it during its free-swimming phase — so completing the full course (and gently raising temperature, where appropriate) is what actually clears it. Super Ick Cure is potent: it can stain and is hard on sensitive, scaleless fish, shrimp, and plants, so dose carefully (often at half strength for sensitive species) and ideally treat in a separate tank. It's the grab-it-now remedy for a classic ich outbreak, especially in a fish-only or quarantine setting. Dosing Guidelines: Dose per the label — typically dose, wait 48 hours, re-dose, then water change — and continue until well after the last spot is gone. Remove carbon while treating; reduce the dose for scaleless fish and avoid in shrimp/planted tanks.
