Yesterday I noticed a funny cloudiness to the pool but chalked it up to the sky being cloudy. Now today it is evident that it is very cloudy (can't see the bottom of the 8ft. deep end). I tested it and expected FC to be about 6, but it's at 0!? This was after adding 128 oz. yeserday. I had also added about 1.5lbs of baking soda to raise the TA a little yesterday.
Test results are:
We are not sure that our chlorine is effective as it's been sitting in our hot garage for the past month. What is the best way to test it? We did pick up some new chlorine but from the same supplier so we're curious to see if it's old or what.
Any suggestions as what steps to take first? This is our second year with the pool, and we've never had the cloudiness before, except at start up in the spring.
