NT Labs Formaldehyde - 250ml

Treats: White spot, Trichodina, Costia and Chilodonella.

When fish show symptoms of a parasitic infection, including white spots along the fins and body, flicking and rubbing, gasping at the surface, or an opaque film over the body. Formaldehyde is highly effective at treating parasites due to its ability to penetrate through the mucus layer, reaching those parasites which would otherwise be protected from alternative bath treatments. It can also be used in conjunction with Malachite to treat protozoan parasites more effectively.
