OK so sump is done. The next project in my build is the fact that this tank is about 9 years old. And over the years of it being freshwater it had produced a ton of scratches and i mean a ton. Its hard to show with pictures but just let em tell you how bad it is. There are deep scratches catchable with a fingernail. There are haze scratches that makes it look foggy from a distance, there are vertical and horizontal scratches. Sooooo... I try to be a perfectionist, so i will be trying to remove these scratches. I have bought the product widely known as NOVUS. I have purchased Novus #2 And Novus #3. I bought a buffing pad that just attaches to your hand drill. Wish Me luck i will be posting pictures of this soon.
