Carol Kerr –
Used Medic to treat a freshwater fish with ich. The treatment worked quickly and my fish recovered within a few days. No side effects on the tank inhabitants. Good value for the small size.
Luke Scott –
Tried it on a marine tank with velvet. The product was easy to mix and the symptoms disappeared after one cycle. The instructions were clear and the treatment didn’t disrupt the water chemistry.
Maria Sanderson –
Very effective against both ich and velvet. I’ve used it twice now and it’s become a go-to product for parasite outbreaks. Safe for corals and shrimp, which is a big plus.
