With Pool Math and Aquachek 7 test strips, I have everything as it should be, give or take the accuracy of the Aquachek 7 test strips. Water is crystal clear, and this just doesn't seem very hard. Yet, I see Amazon reviews on the test strips saying that you still need a 'real' test kit. Why? I feel like I've got everything in near perfect harmony with the help of Pool Math. Maybe you need a test kit if you don't use Pool Math? Just wondering if I am missing something.
By the way, my pool is approximately 31000 gallons with a deep end, an 8 foot round spa, a grotto/waterfall, and a tanning ledge with bubbler if that makes any difference to the ease or difficultly of adjusting pH, Chlorine, and related items.
