Provide fast oxygen support when your aquarium needs it most with Sera O2 Plus (Oxypur) 250ml — an easy-to-use oxygen-releasing treatment designed to improve living conditions during acute oxygen shortages.
Aquarium inhabitants and natural decomposition processes constantly consume oxygen. High water temperatures, heavy organic pollution, overcrowding, or oxygen-consuming disease treatments can cause oxygen levels to fall dangerously low. Even a minor shortage can stress fish, while severe oxygen deficiency may become life-threatening.
Simply sprinkle Sera O2 Plus into the aquarium water to release oxygen immediately. The improved oxygen supply helps fish breathe more comfortably, reduces stress, and supports faster natural breakdown processes within the aquarium.
Better oxygenation also helps beneficial microorganisms break down organic waste and sludge more efficiently, supporting clearer water and reducing unpleasant aquarium odours.
