So I just bought a 300 gallon acrylic (summer project) tank. It's a lil rough and I need your help. Lets take this one step at a time. The first thing I need to do is clean this tank up. I'm not afraid to use chemicals in it since it will have plenty of time to evaporate and i plan on a few water fill ups before I move it into the house. What do you guys suggest to fully clean this inside and out. The next step is to try and buff out the marks and scratches in the tank. I know there is a product out there for this i just cant remember what it is. So these are where I want to start once this is done ill update post pics and ask more questions.
