I've started to set up the 54 gallon corner bowfront I've been working on. I've never worried about leveling a tank before because my previous tanks have been a lot smaller. I got the level out for this one, and this is what I found. This is with the level about in the middle of the front bow part of the tank:
Across the back corner shows the same results, but putting the level across both side corners of the tank shows them to be level. I'm confused as to whether or not this is enough of a difference to need to be leveled, and I'm even more unsure as to how to do the leveling. The tank sits flush on the stand, and I think it's actually the floor that is not level. What do I do?
