Ultimately, all decisions about your pool are your own--we can only suggest.

However, if your pool is still green and cloudy, it means your chlorine is being "eaten" killing it. If when you test you see chlorine levels have dropped a lot from the last test, your chlorine is being consumed.

If, however, your water is clear, and despite the difficulty with the dilution test (Hold a white card behind the cell--it may help), you don't see much change in the test, it means your chlorine is holding and it's probably safe to swim in it.

But, if the chlorine is high, wear last year's bathing suits. You'll be ok but the suits may fade.

But the ultimate decision and responsibility is yours. It's your pool and we aren't there to see it.
