Well, no so new to me and many other folks, mostly from the pond folks.
Sodium percarbonate - Wikipedia, the free encyclopedia
This is a contact algicide, meaning you toss it in as granular pellets which land on plant leaves, kill the algae and then it sloughs off.
Now it does give off H2O2 and raises KH.
So you can not go wild using it, but you can spot treat by dropping some powder in each region and in a few days, maybe a week or so, you can clean up the algae.
I've seen it clean up lakes and ponds of attached algae on rocks and plants very effectively.
I've tried it on several plant species, it had no effect, it very well might harm some plants and some one is bound to add too much and kill their fish and plants because they think "more is better" or just do not bother to read the instruction label.
No way to prevent folks from making mistakes.
It looks a bit like a KNO3 powder, you just take a jar and spread it out in the infected area, it'll sink and in about 1-2 hours, the deed is done.
You can retreat the following day etc so there's no rush to do the entire tank all at once, just realize that it does raise the KH a fair amount and adds H2O2. However, like liquids, this slowly and locally adds the carbonate and the peroxide, this causes both high pH/strong oxidizer and then slowly dissipates into the tank water.
I was hoping it might kills weeds, unfortunately it did not, but cleaned off the weeds really well.
Cheaper than heck too, ADA would sell a tiny bottle for 18$

I tested it for killing weeds for Green Clean some years ago.
I'm not big on killing algae like this in planted tanks and have not been willing to test it under plant tank conditions.
Still, it's much easier and better than bleach.

This gives some indication about how to use it.
I'd do a water change before and after just in case.
It will kill any species of algae BTW, hair algae etc.
