Thanks everyone for your responses. We have decided to go with the 30' pool. I do have the room in our backyard, and then some, so thanks for your concern. I have experience with taylor test kits and chlorine because we also have a spa. Thankfully I got the kit with pool chemicals in it also. I think the biggest problem so far is dealing with the city I live in. First they have to have a drawing to scale of our plot with deck and pool on it. Next I have to outline on the grass where the pool is going and they will come out and have a site inspection. Then once the pool is erected, we're not to fill it until they come back and inspect it again. Have you all gone through this to? I think it's way overboard. Denise
