I saw this video on youtube of a guy pouring hydrogen peroxide into his fresh and saltwater tanks and it was eating away the algae right away, green hair algae. Do you guys think it would work or should i not risk it?
Peroxide can be used at the proper dose during a power outage to add oxygen to a tank. I have never heard of it being used in anything other than emergency power outages, furthermore I would not add peroxide to a tank unless you know EXACTLY what you are doing.
Hydrogen peroxide is basically just water with an extra oxygen attached to it. The oxygen bond is weak and it dissolves easily to become water and oxygen.
