just wondering?? what you you setting the tank up with?? what filter are you using?? you can cut the time in half or better by using the following.......

you can speed the process up by a LOT by using an aged sponge filter in your new tank.

or if you are using an undergravel filter, take some (a cup or more) gravel from one of your other tanks to add to the new one.

another way to speed things up is to use plants in the new tank. plants are always good to use in new tanks.

also put the tank light on like you would normally (8-10+ hours a day), lighting helps out a lot in building up good benificial, algae

good luck with your tank
