Keep reading and find out everything you need to know about hydrogen peroxide aquarium dosage.
What is Hydrogen Peroxide?
Hydrogen peroxide is a weak acid characterized by its strong oxidizing properties. In its pure, concentrated form, it is a pale blue liquid that is slightly more viscous than water. However, when it is diluted, it appears completely colorless.
As for use, it is used as an oxidizer, bleaching agent, and antiseptic, and can also be found in various forms ranging from 1-90% H2O2. Keep in mind that all concentrations higher than 20% can be corrosive and harmful to your hands.
Although a potent and a bit toxic chemical, you can still use it in your tank. It is only important to pay attention to the fact that you have proper hydrogen peroxide aquarium dosage. You will find more about it below.
