Removing Coralline

[Leah]

Once you get a handle on the coraline I get this stuff from Lordco it is white and
comes in sheets that are about 8-10. when I do a water change I cut apiece off
and run it on the bottom of the tank, top and where ever I see yuck. I swear by it
I think if using it on acrylic I would test a small area first. Hope it works *
