Treating algae with H2O2

I have heard that h2o2 is an effective treatment for algae covered plants. Is this true? I want to move a couple mid ground plants from my old 10g to my new 36 but they have black/brown algae on their leaves and wanted to treat it with something before moving them.

If h2o2 is not the answer, what would you do to the plants before moving them to treat the algae and hopefully avoid moving it into the new tank?

I read about that somewhere myself and from what I understand it's just hydrogen peroxide. It's supposed to be a safer alternative to bleach because it dissolves into just oxygen and water while bleach will leave a residue. I'd love to hear more about this approach! I've used a mild bleach solution on my anubias nana before with out harm but really don't want to go that rout again.

I used this to spot treat BBA in my 55 just used a small syringe (no needle) to dose the affected area with all pumps turned of let sit for 10 min or so then turn the pumps back on. did this twice over a weeks period and it killed off the BBA on the few affected plants.

I've read that you can dip your plants into a mix of 50:50 water and H2O2 for a few minutes rinse and place in tank, I'm sure most plants would be fine but there are some that are more delicate then others.

I can't see why H202 (hydrogen peroxide) would not be an effective, relatively safe approach for treating plants to remove certain types of algae. I have always spot-dosed Seachem Excel for this purpose, but H202 should also do the job. I do know that it is very effective getting rid of cyanobacteria ('blue-green algae'), for which I've used it.

It works quite well and pretty fast, good preventative dip for plants too.
