What kind of filter are you going to run? Go get it and set it up in your stablished tank for 2 weeks or so, also add some more rock and gravel or sand. That way in 2 weeks you can take all that extra material and use it as seeding material in your new tank.
As previously said transferrig just water wont do you any good in the beneficial bacteria (BB) aspect. Seeding material on the other hand can definately reduce your cycling time to maybe just under 2 weeks.
Thats what happened with my 29 gal
, yours might take a bit longer, or not, but thats the way to go. Then follow recommendations for fishless cycle the process will be the same just that you'll have a lot of BB to start with. Hope to hear how it goes.
