Sera O2 Plus, 250 ml

Sera O2 plus is a powdered water additive that increases the oxygen supply in freshwater aquariums.

The new aquarium care system from sera solves all problems in the aquarium with just one product per step:
- With an improved active ingredient formula
- simple and effective application
- scientifically tested
- for optimal and comprehensive basic care
- for the creation and permanent maintenance of species-appropriate water conditions
- for immediate help in case of difficulties

Sera O2 plus serves as an emergency aid for acute oxygen deficiency and reduces stress through an optimised oxygen supply. It can be used easily and safely and supports the breakdown of mulch.

The breathing of the aquarium inhabitants as well as other natural degradation processes consume oxygen constantly, even aquatic plants consume oxygen at night! Under certain circumstances, life-threatening undersupply can quickly occur.

These include very high water temperatures, a strong organic load, but also oxygen-consuming medication applications. While even a small undersupply causes stress, an increased and extreme undersupply very often leads to the death of all aquarium inhabitants.

Sera O2 plus is simply sprinkled into the water and immediately adds oxygen - the living conditions for all aquarium inhabitants are improved quickly and effectively. Afterwards, the main cause of the lack of oxygen should be found and remedied. In addition, degradation processes run more effectively with a good oxygen supply, so that the aquarium water remains crystal clear and has no unpleasant smells.

Our expert Oliver Knott recommends:

With Sera O2 you can supply oxygen quickly and effectively in emergency situations and thus possibly save the life of your fish - until you have found and rectified the main cause of the original lack of oxygen!
