Kids have been in my pool a couple times and complain of sore/dry eyes after they get out. Since all the other tests seem OK (results below), I presume its time to deal with pH. We opened the pool 2 weeks ago so Ive been waiting for the water to clear up. It is now basically crystal clear and Im letting the FC fall by itself. Turned off the SWG, etc. During the SLAM process I was using liquid shock.
Current test results:
FC - 10
pH - 7.3
CC - 0.5
TA - 50 (waiting to get pH in line before upping this)
CYA - 40
Last night I added about half of the amount that pool calc recommended to get my pH to 7.5. Waited an hour (pump on), re-tested and still no pH change. Let the pump run overnight, re-tested this morning, still no change in pH. Our pH reagent is 1 year old and has never seen heat or sun.
Is the FC level causing an issue with the test? I always thought it would cause it to read higher instead of lower, but maybe not.
Or is the reagent suspect? Luckily thats an easy one to find if I want another bottle.
