Ya 1ml per 10g is the same I used on my tank for dinos . Keep in mind it will knock it back for a bit, but unless you figure out the source of it, they will just come back.
I dosed mine on 3 occasion with full blackout during it, and they went away for a few weeks, but eventually returned. After the 3rd run of it, the dino developed a resistance the the peroxide and it no longer worked. I tried several other things too after that, including DinoX, which killed all my bryopsis, but didnt phase the dinos

.
In the end the only thing that really worked for me against the dinos was a UV sterilizer
