As long as you don't overstock your tank then that filter should work fine. Actually I beleive that the filter you have is rated for up to a 30 gallon tank. Also if I remember right it filters about 170 gallons per hour (GPH). So if you do the math on that one then your water gets filtered about 8 times an hour. You should be in goos shape as long as you take care of the tank.
Good luck on the new tank.
