Jan and Al are right and not much you can do about them and it won't take away from the enjoyment you will get from your pool.

But, I understand being concerned about the imperfections. Kind of like having babies. Especially with the first one, you want (and expect ) that everything about it will be perfect. It's never gonna wear anything other than a precious little Gymboree outfit and your baby will never wear a stained bib or a stained onesie, etc. Yeah, right. Maybe that will be true the first week. But, after that, EVERYTHING will have stains and you'll be so tired that you won't care. Been there, done that. Three times, although after the first baby, you know upfront that there is no such thing as perfection.

Same with this brand new pool -- your baby. It's gonna be ok.
