Herein, is hydrogen peroxide safe for fish?

Hydrogen peroxide is the chemical compound H₂O₂. Hydrogen peroxide's highly reactive nature, similar in some respects to the reactivity of potassium permanganate, makes it ideal for use in aquaculture against numerous external fish-disease-causing organisms, but with similar concerns regarding toxicity.

how do you treat an aquarium with hydrogen peroxide? Depending on the algae species, we recommend different dosages:

1. In the case of blue-green algae: 8 to a maximum of 15 ml of the 3% solution of hydrogen peroxide per 50 liters of water.
2. In the case of green algae: 25 to a maximum of 35 ml of the 3% solution of hydrogen peroxide per 50 liters of water.

It was suggested that it could be hydrogen peroxide poisoning. In low concentrations, "standard" (1-3% solution) hydrogen peroxide will not kill healthy fish. The trick, of course, is establishing what a safe dose is; as with any chemical, it can be overdosed.

How long does hydrogen peroxide last in aquarium?

Conclusion: This amount of H2O2 does not decompose fully in aquarium water after 2 days.
