razor blade on an acrylic tank?

[drewster]

Can i take a razor blade and scrape off coraline algae off the sides of my acrylic tank or will it scratch it very easily?

If you even LOOK at an acrylic tank wrong it will scratch. Try using a credit card or similar card. A razor blade,even if you are careful,will destroy the tank. STEVE

No way on the razor blade, the credit card is the way to go.
