Ok. I thought you meant pH of 8. My bad.

If everyone is sneezing, I bet it is pollen. I just did a google search for 'pollen counts southern ohio' and found a page on the Weather Channel's website that lists it for various cities in the state. I didn't know what city you were in so I just put Cincinnati in and it said moderate to high.

You can try it. Here is the link. http://www.weather.com/outlook/healt...drilldown/ohio
Then, just click on the first letter of your city's name and you'll be able to find the pollen forecast for your area.

But, having said that, still feel the floor the next time you are in the pool and see if you note any slipperiness.

Hope this helps.
