What size is your tank ? Before you are so quick for somone to fix the scratches assess the amount of scratches and how deep they are. Furthermore, are they on the outside or inside ? I was in the same situation you were over a month ago. Did a lot of reserch and a fellow Mr (thanks Chris) helped with a lot of trial and time... A lot of the scratches can be taken out with the Novus 1,2,3 formula(this can be used on the outside of the tank or when the tank is empty). Or if the scratches are too deep you can use a 1/2 sheet palm sander and start with a 300 grit paper and sand you way up to 8000-12,000. I found that if you could clearly feel a groove with your finger then use the sanding method 1st and finish with the polishing method(novus 1,2,3). Most body shops will have these papers readily available. If you take this route also cool the acrylic(use water to wet the area constantly) If you can't find paper above 3000-4000 grit and the area is small you can use the paper that is contained in the pentaire acrylic scratch remover kit. This can also be used when the tank is full with water. I recomend getting this kit, it will come in handy.
