Moving my tank just 2 more inches off of the wall. Help.

Do it during a 60% water change. Take the hood off, and pray that your rocks are steady.

Rocks are pretty low to the substrate.

For reference, I have a 75g rectangular tank.

Thanks.

I probably would not take the chance. You'd definitely have to be able to slide the stand/tank as a unit. Maybe if the floor was a hard, smooth surface and sliding would work easily. Then, I'd drain the tank to 2" of water and have 2 people holding the tank onto the stand so it doesn't topple off, and slide from the bottom of the stand near the floor one side at a time.
