Ok, we do plan on putting it in on a sunny day. I appreciate all this help, I am completely stressed about doing this right and my hubby really didn't want a new pool so I want to be sure I don't stress him too! However, IS it supposed to be that way (small with gaps) or is is supposed to be just right to start with? If he sees the wall bend and buckle, I am sure to be blamed for doing or ordering something wrong!
