1. Of, first on the to-do list is finding out where to place the hole for the air pump inlet. I suggest having a friend help by holding up the tub with the air pump against the side to a bright light so that you can see where to punch your hole. You can mark it with a sharpie or punch it up in the air, that's what I did.
!!! careful though, don't go too high or too low or the alignment will be off. I found that a tiny bit low works best !!!
