New tank concerns?

[BF McUmber]

For background, petco begrudgingly took my first 40 breeder tank back that had scratches in it when I bought it.  The first one was manufactured in 2020. 

So,  I went to a different petco while on vacation and got the best of their 8 available tanks.  (The employee was very helpful in the tank selection.) The sticker on the tank says it was manufactured in 2018. When I filled it up, all of the wall seams turned half speckled white as you can see in the picture. Does anyone have tanks in service that have this type pattern when filled?

@lefty o should I read that as you also do not think it is a concern? 

[lefty o]

i dont think its too big of a concern, more cosmetic.

Wouldn't bother me either.
