I've used it. I used it as a spot treatment from a syringe a few times - worked ok on cyano. I have a spot on my plumbing where GHA loves to grow - I was squirting it daily for about a week and it was tapering back, but then I traveled and quit so I did not eradicate it. In those cases, I was administering 10ml into my ~120gal system.
I tried it in a QT that had green water. Really just to see what would happen. It had a 6 line wrasse as a permanent resident. 1ml/10 gal once a day did nothing for 3 days, 2ml/10 gal daily helped a little but nothing impressive, 2ml/10 gal 2x daily took care of it. But then I had an ammonia spike, and did a water change. While I did I took the intake off my pump to clean it and the wrasse swam in. He was a bully and was never going in the DT, and frankly caused me issues in QT, but I certainly didn't mean to kill it - he was my most interesting fish to watch.
I do not know if the peroxide killed off too much bacteria, or if it was the transformation of the green water/algae from nutrient user to nutrient source - probably the latter had more impact than the former, and I really should have done the water change a day earlier.
Anyway, I'm pretty convinced peroxide is safe to use at 1ml/10gal once a day, and I would do twice a day with close observation for a limited time - since it breaks down quickly, more frequent dosing seems a safer way to up the dose than a higher volume in an operating tank.
