NT Labs Formaldehyde 250ml treatment for Parasites and Flukes. This is a fantastic anti-parasite treatment, especially when it is combined with Malachite. As a result of its ability to penetrate mucus and reach parasites that would otherwise be protected from other treatments, NT Labs Formaldehyde is particularly useful for the treatment of flukes.
