i have coraline spots on the front glass of my tank that won't come off with a algae scrubber does anyone know what will work to take off stubborn spots?
Well, I am scared to use them myself, but I hear razor blades work well. Also, instead of a scrubber, they have algae scrapers. That I do use, and it seems to work for me. They have a plastic blade.

If your tank is glass a razor blade will work. I use a credit card most of the time. Does take some scrubbing sometimes.
Razor blade. Just be careful not to scratch the glass. You will end up small cuts in the glass where algae can/will grow and you won't be able to clean. It is easy to clean with a razor blade, just need to be paying attention to what you are doing.
