There isn't much bacteria in the water you move from one tank to the other, gravel will help more if you have an undergravel filter in your 65. If you have a powerfilter on your 65, the best thing you can do is once you get that new tank cycling (declorinated, added ammonia, filter going, right temperature) swish that filter cartridge in the new tank from your old tank every few days. Each time you transfer bacteria from an established tank to a cycling tank it speeds things up. The most bacteria in your established tank is where the water flows through/past the most, meaning your filter.
Here check out this thread...I got my 46 done in two weeks!
