I need a good magnetic glass scrapper for algae ... any suggestions? My current scrapper just can't get the stubborn patches of brown diatoms (or whatever they are) and my arms/hands are huge so going in with a razor can be more invasive and slopier than I like.
Does anyone have any experience with this one?
