Yes, order the stabalizer online - you can often find free shipping. I do a lot of my shopping online since I live in a small town too. You will also have to get some calcium in the water too. Walmart sometimes has calcium, or if you have a lowes, they carry it. If not order that online too - you need between 200 and 400 for a gunite pool. Use enough to get you to 200, sometimes what it calls for will take you over 200! So I always go for less. You should add the bleach now, you don't have to wait.
