Medic is a highly effective water conditioner designed to control external fish parasites in both marine and freshwater environments. It targets common issues such as Marine Ich (Cryptocaryon irritans), Freshwater Ich (Ichthyophthirius), and Marine Velvet (Amyloodinium ocellatum). This treatment contains a reef-safe oxidizing agent that is particularly effective against the free-swimming stage of parasites, making it highly efficient in disrupting their life cycle. Medic is buffered to maintain physiological pH levels and does not harm invertebrates or nitrifying bacteria, ensuring safety for all tank inhabitants.
