Levelling a 150 gallon + 57 gallon sump

[Alexander1312]

I have bought an Innovative Marine 150 gallon plus the RFS39 sump from them (57 gallon capacity). Two picture show the current levelling of the tank. Does it both need to be exactly in the middle?

Depth of the tank

Length of the tank

"Depth" looks good, the "length" needs to come up a bit on the right. It impacts the level of water in the tank which impacts overflows, wave pumps, but no it doesn't have to be exactly in the middle, ime. The first depth looks good enough for most applications.
