Algae problem

[myost20]

my 260 gal acrylic tank has been over taken by calciferous algea on the front viewing panel. Any easy way to remove without scratching the tank?

lots of manual labor and a credit card or plastic scraper, anything metal will scratch it

Credit card works really well for acrylic

Thanks for the help.
