Acrylic Aquarium chisel repair? I have a really nice Acrylic aquarium that im planning on setting...

I have a really nice Acrylic aquarium that im planning on setting up again but it has a scrape across the inside right in the middle and it drives me crazy. Its not super deep but next to two sets of lights on it lights it up and its distracting. Anybody know how to repair the scratch?
Can you update me more in the region...
Answers:    you have to sand it out. use a really fine sand broadsheet like 1000 grit, then move about to 2000 then 4000 then use steel wool 00 consequently 000 , 0000. that ought to do it.
Help near electrical pricing?
As above but then move onto car polish for the really fine finish. If you hold a buffing wheel that can also finish the polishing.

should be able to obtain it looking like new !
