You will get more responses from better knowledgable people on AG pools but here are my initial comments. I didn't look at the site for details but Mom is right about the pump and filter sizing. Very critical decision. Always better to go bigger filter, smaller pump. You save $$ on electricity and don't ram water through an undersized filter. Here is a thread that may be useful in understanding liner thicknesses. What I learned about the term 'gauge' in the pool world threw me.

Do a lot of research on poolforum before you buy and you will stand a much better chance of being happier in the end. Look through the other forums 'pool construction and repair' and 'pool equipment and ops' as there is a lot of info on equipment that is applicable to any pool type. Any questions, don't hesitate to ask.

Only see you have 4 posts so if we didn't say so before...Welcome to the forum.
