It depends on the depth of the scratch. It is extremely difficult to remove deep scratches without having to remove a lot of acrylic and potentially weaken your tank. Light scratches are much easier. Start with novus 3 for heavy scratches and work you way to a novus 1 to give you a fine polish. You can use a high rpm corded drill bit with a foam polishing pad attachment and patience. There are a lot of videos on the web.
Ideally do it with a empty tank as the novus creams are likely toxic to your tank inhabitants.
