I have a new Intex vinyl above ground pool, 12,600 gallons, SWG with ozone by Intex. Water is clear, beautiful and does NOT smell like chlorine (chloramines?), yet my eyes burn. Very little sunscreen gets into the water. The pump & chlorine/ozone generator run 8 hours in daylight per day. All I have are test strips. A test strip dipped in before the pump came on and the sun rose above the horizon returned the following results:
Total hardness 250
pH 6.8 to 7.0 (which is surprising since I lowered pH to 7.4 by adding about 3/4 box of Borax 3 weeks ago, but it is early morning and it has been raining a lot lately.)
CYA 50 (which is also surprising since I originally poured in about 50% more CYA than was called for)
I know I need a better test kit. All good things in time.
Is the low pH what is causing my eyes to burn? How much baking soda do I add?
MAJOR EDIT: I didn't trust the test strip, so I used 3 different pH tests from my saltwater aquarium and all three said 7.5 - 7.6. Another saltwater aquarium test said the alkalinity was in the 2.0 to 2.3 range measured in Milli-equivalents per liter.
So if it's not low pH, what's making my eyes burn?
