Welcome! As
@mknauss said, the strips are known to be very inaccurate. The fact that you just filled and it's saying you have 1ppm TC and 0ppm FC proves this point. That's a ridiculous result on a fresh fill of 1500 gallons.
Personally, after having seasonal pools for the kids for years prior to having found TFP, I don't follow the seasonal pool guidelines but rather treat any pool as if it's not seasonal. The seasonal guidelines work because these pools are small and can be drained and refilled easy enough if something goes awry (algae/green water).
Couple of questions for you... have you added anything to the water yet? If so, what did you add?
If you haven't added anything, put 13oz of regular (non-scented, non-splashless, no additives) bleach into the pool with the pump running. Pour it right in front of your return, slowly. You will need to add bleach daily but the amount you add will change once you get the following into your pool. We use
PoolMath for calculating how much of anything to add.
You will want to get some stabilizer (CYA - cyanuric acid) into the water as soon as possible.
Pool Math (this is the web version) says to put 12oz by volume of dry stabilizer in to reach 40ppm. You may need more than that in your location, but that's a good place to begin.
Have the kids get in and splash around, your pH will probably rise after that. Don't do anything for pH just yet. Aeration (bubbles) raises pH.
Pool School is awesome, so take some time to read up there. The forums are a wealth of information as well, with super nice folk who are happy to help.
