Welcome to TFP!! I was in you position a few years ago and actually closer to your exact position last year as I went to a much bigger pool last season. So, how are your do-it-yourself skills? I understand you hiring someone to put the pool up. Perfect idea. Unless you have alot of help, you will most likely be better served by having someone else put the pool up.
Electricity. Here is were we start clearing the room from everyday DIYers to the "real" DIYer. I did my own electrical service from the box to the pool. Yup, lots of digging, trenching, cussing, bleeding (just occasionally) and one case of beer to have it "approved" by my local electrician. If you city allows it, you could do most of the rough in (as in rent the trencher, buy the underground cable, blah, blah, blah) and have a licenced guy do the final if your unfamiliar or simply don't want to do the electrical thing. Honestly if you have an electrician you know, have him tell you what to get and tell him you want to save money by putting the cable in the ground and he'll make the actual connections. It's still money to him and very easily made, quick, and will get him future business with good recomendation to your friends. A good guy will "assist" you and let you do the really hard part and he can finish the rest. Just ask him what two spot to have the lines come out of the ground and let it go at that. You will save some money potentially that way.
Let's talk pool. Have you noticed how many people have said something about a test kit? As someone who didn't have one for the first two years of pool life, please, right now, stop reading this and order one. Support the foruma and get a TF-100 and you'll need the Taylor salt test too with that SWG. You will still need to read up here on proper chemical levels. You will need some stabilizer so get some and use the caculator to figure out how much salt you will need for your initial fill, than have another bag around for top off now and again.
Testing is THE key to your pool satisfaction. Without it, your pool will suck. It WILL turn green, look bad, you'll get Crud from wife, kids and neighbors. Testing tells you what you need to add and using the calculator you can then KNOW exactly what you need to add or subtract. Since I got a proper test kit (I have the Taylor 2006), my pool was the most fun it's ever been. EVERYONE HAD FUN. Testing is the key.
Final two cents: You very much need that next model up on the salt generator.
Wait, I'm not done......heat......ever think you may want a little heat? Oh, I know, you're going to use one of those solar heaters. Yes, those will work, but what about late October and the kids REALLY want to go play in a late October day in the upper 70's or 80's? While you have the trencher and the utility people have to mark anyway. Get some of the yellow poly gas pipe and again trench and just cap it off close to the meter and the pool area.....that way you will be ready for the upcoming Natural Gas pool heater in your future. Something to give honest and frank discussion to. And no, you don't need to use it all the time either....
