Top trim not completely *Flat*

[Charley Diesing]

The top trim of my Planet Aquariums custom 210-gallon tank isn't completely flat. This is causing me to be insecure about what exactly is "level". For example, I can get both "length" sides "level" while one "depth" side is level and the other is un-level. I can physically see how the top trim isn't completely flat when putting a straight edge on it.

I'm within the "rings" on the level. But I want to get it perfect.

The stand is a metal stand from planet aquariums with adjustable feet.

Any suggestions?

Use the water level to check it.

Use the water level to check it.

Yup.. Or a tape/line projected from the inside bottom glass or whatever..
Water is the best though.. Its guaranteed to find level
