The fish tank is made of acrylic acid. Can I use the scraping board?

I can't. The fatal disadvantage of acrylic fish tank is that it is easy to produce scratches. Cleaning the algae on the fish tank wall with scraper will leave subtle marks on the tank wall. These marks can't be repaired and remain on the cylinder wall for a long time, which seriously affects the ornamental value and can't be used. Fish tank, a kind of water tank for live fish, has a transparent cylinder, mostly made of glass, and can also be used to raise tropical fish or goldfish for viewing.
