CRC makes Guaranteed To Pass for both gas and diesel engines. It is made to be used before emissions testing to pass but can also be used as an additive just to clean up the fuel system. I have found I gain about 10-20 miles extra per tank (with a 20 gallon tank) after using it for the next 2 or 3 tanks.
Move everything from your 20-gallon to your new tank. Everything. Filter media, gravel, plants, decorations, water, everything. If you don't want the gravel to stay permanently, you can put it in a nylon stocking. If it's the same kind of gravel you'll be using in your new tank, just mix it in.
