Acrylic tank is fuzzy, need some help

I have a 40 gallon acrylic that is very funked up from the previous owner I got it for free so cant complain I just use it as a hospital tank and it does the job for that.
 
:read:aquarium safe sandpaper?

Are you asking if I said the sandpaper was aquarium safee? Because I was talking about the buffing and polishing compounds being non toxic...

But if you were wondering if the sandpaper was aquarium safe that is a good quaetion... All the glues and stuff they use on it does bring up that question.
