Providing it is well ararated no it shoulden't.. BUT in a new 20 gal tank with agressively growing algae and such the )2 level can be depleted at NIGHT time.. this is why you have to make sure your surrface agatation is high at night also (or run a skimmer).

I am sorry for not providing enough information. There is no way you could have known that YES the tank was new, but the contents were not. The contents were everything out of my 10 gallon nano, with a number of gallons of water out of the 50. In other words it could be called an existing tank with the addition of some substrate. ops:
