Description
Aquasonic Marine Oodonex 100ml
Aquasonic Marine Oodonex 100ml (SKU: AQS30) is a specialised marine antiparasitic medication formulated specifically to treat Marine Velvet disease (Amyloodinium ocellatum) in saltwater fish. Marine Velvet is an aggressive, fast-spreading dinoflagellate parasite that attacks the skin and gills of marine fish, often causing rapid mortality if left untreated. Marine Oodonex targets free-swimming dinospores and attached parasites, providing fast relief from gill irritation and skin damage.
Aquasonic Oodonex is a potent treatment designed for marine aquarium fish affected by whitespot (Cryptocaryon irritans) and Oodinium (marine velvet disease). This copper-based formula is intended for fish-only marine aquariums, providing fast and effective results.
Important: Not suitable for reef tanks; avoid use with reef systems, corals or invertebrates.
