Here a link for those who want to read more about "dry h2o2"
Yes, it raises KH via the Na2CO3, sodium carbonate.
But relative to the tank, it's not much and we do a water change at the end of the treatment and the KH goes back down.
It's somewhat like adding baking soda to increase KH.
Perhaps that has some impact on algae, but not much I'd say.
I have some species of algae I've managed to culture to try on in a tank. I keep a tub of weeds in back and some get some algae on them. While no new algae will grow if I take these and place them in my planted tanks inside, I'm less concerned about that.
I just want to see a good method to kill the algae with a contact herbicide.
So I'll stop the filter, sprinkle, wait and see.
The algae is a nasty black hair like algae, more like Staghorn, Compsopogon, which we all know and hate.
