Is 10ml/per gallon an accurate dose? I though it was more like 1:1?
3ml/gallon is usually more than enough. Too much and you are risking damaging the plants or fauna. 1:1 for too long of a time can completely melt plants down. So if you go this route, it's better to do it outside of the tank and rinse within a few minutes. Remember that this is an oxidizer and not selective on what it goes after. Better to go slow and easy than to bomb the tank.
