Cool, I decided to go with 45mil, just to be safe. Added $140 to my total, but I don't want to have to do it over anyways later if the pond tears.
Here's the new list of what I'm getting:
45mil liner, Firestone, 20'x25' = $190 + $79.36 shipping = $269.36
20mil liner (for bog filter), 10'x12' = $24.99
3500gph Beckett Pumps, 2x $89.99 + $29.90 shipping = $209.88
4500gph Skimmer = $185.00
Total = $689.23
I also opted for a skimmer with a 9" weir vs. a 6" weir, and 700gph greater capacity. It's only $15 more, so I think its worth it.
I'm also going to be building a new deck starting in a week or two, so things are gonna be crazy around here for a bit. I'll post pics of everything I'm doing. It should look really nice once I get the pond and deck done
