What chemicals did they give you? Tell us ingredients and not just product names. For today, I'd suggest adding aquart of plain, unscented household bleach and then letting it circulate for a half hour or so and then you can let the kids swim. Once the pool is full, you might want to add another quart, again waiting a bit to let it circulate. You'll probably need to add some more this evening since with no stabilizer in the pool, the chlorine isn't gonna stick around long.

Do you have a test kit?
