After our fish tank was all set up and filled with fish, I noticed that the fish tank tilted slightly toward the left, so the water level on the left is about half a centimeter higher than the water level on the right. I'm just wondering if this would affect the lifespan of the tank. I used a level and measured at the base of the tank stand, and it showed that the tilt began there, so the tank itself isn't in any type of stress itself. I'm guessing maybe my house isn't leveled. Since I think it's too late now to adjust the tank position, should I just start stuffing paper piece by piece under the left side of the tank? Or would the tank be fine
