While you are waiting on the install, do yourself a favor and go ahead and buy a good test kit so you'll have it when the pool is ready. Click on the Amazon link in my signature and get either the Taylor K-2006 or the K-2006C which is the same kit with larger bottles of some of the most used reagents. Buying through that link makes the Pool Forum a little money on the sale which helps keep the forum up and running. Only buy if the seller is Amato Industries, however. Some other sellers are substituting the K-2005 which you do NOT want.

Let the pool place do the build, but don't let them start you up chemicals-wise. When your test kit arrives, go ahead and test your fill water and post the results here. It will help us advise you of what to do with your freshly filled pool and will also give you practice with running the tests. Don't do the CYA test, though. Your fill water will have no CYA in it and you'll just be wasting the reagent.

Buy several jugs of Walmart generic bleach. Also, buy a box of 20 Mule Team Borax (laundry aisle at Walmart), some baking soda and also some CYA -- probably a 5 lb. container. (Sometimes labeled as conditioner or stabilizer. If the ingredient label says cyanuric or isocyanuric acid, it is the right stuff. Don't let a pool store talk you into buying anything else.
