We received a really good question the other day concerning the use of hydrogen peroxide H202, and it’s use in ponds and water gardens. Specifically, what about using the drug store liquid peroxide that you normally would use to disinfect scratches and scrapes. So here’s a video that covers the various uses of hydrogen peroxide in ponds.
Long before any commercial products came on the market that contained peroxide, I suspect any good do-it-yourself loving pond owner would have probably tried it for algae control.
You gotta love the open minded experimentors of this world…they move us forward.
With that said, I generally don’t recommend using store bought H202 simply because I try to error widely on the side of caution with such things. First of all, the normal 3% solution is pretty light weight and may not do very much to help with algae. Secondly, a lot of this stuff isn’t just hydrogen peroxide and some will contain stabilizers and additives that I don’t want in my pond.
So that leaves a couple of options.
