NT Labs Marine Anti‑Parasite is a copper- and formalin-based treatment designed to combat marine protozoan parasites such as Cryptocaryon (marine white spot) and Oodinium (marine velvet). It employs chelated copper therapy enhanced with formalin for rapid parasite control in fish-only or hospital aquaria. A single 100 ml bottle treats approximately 400 L (about 88 gal) of marine water over a 12-day course. It’s not suitable for tanks with invertebrates, live rock, or copper-sensitive species.   How to use: Check water quality using Marine Lab Test Kits before use. Remove adsorbent filtration media (activated carbon, phosphate remover) from filters for the treatment period. Turn off UV filtration and/or ozone generators if present. Turn off protein skimmer for a minimum of two hours after each application. Maintain good aeration throughout. Use provided pipette to measure required dose and slowly add dose to aquarium. Use table provided to log progress of treatment.
