Alright, I'm doing the final mark ups on my sump and it would really be helpful if I could "draw" on the tank.
I noticed that my LFS was using what appears to be a regular ol sharpie. I know it would work, but would it be of any harm to the water/inhabitants? Could the Sharpie chemicals "come" through?
