I have a 90 gallon tank and ran across a nice deal on a used 120 and I am thinking about upgrading. My questions are #1 Advice for moving everything from my 90 to the 120. The new tank would be going into exactly the same spot as the 90. #2 What is the best way to move everything over (including the sand). The 90 has only 1 overflow and the 120 has 2 so I would need advice on how to plumb the double overflow. #3 I am also wondering if the aggrevation is worth the addtional 30 gallons? Looking for advice from someone that done this before. My only move was from a 29 gallon nano cube to the 90 (and the guy from LFS in Chatt did most of it) Thanks Bill
