It's a finite element analysis (FEA), I designed a template which works with the software and does a simple analysis based on basic tank design for whatever size I desire. I can also add bracing and various other features if needed. Front to back or side to side you may see up to two mm total but it bows out less at the top so it'll probably be close to about 1mm total. Basically you won't really notice it. You may notice a little difficulty in macro photography in the red area but that's it.

I'd vote for option #2, you can build a center structure of rock to cover the return outputs.
