So, am I ready to ROCK???

The CYA level may be more than 100 since that is the limit of the test (the black dot could disappear before one adds enough "cloudy" mixture to the tube to even get to the 100 ppm line).

Unfortunately, the only real way to lower the CYA is through dilution which means partial drain and refill. However, since this is near the end of the pool season and winter closing is approaching, the pool can just be made to have higher than usual chlorine levels until winter closing. Then the CYA may drop over the winter (for reasons that are not fully understood yet). If the pool is in an area where there are winter rains, then these can be used for dilution via overflow (but if it's in a freezing area, then that may not work as one usually lowers the water level below the skimmer and inlet returns).

Hi ya Richard.

Summer still here in Central Sunny Texas.



Water temp is 84 when I checked yesterday.



We can actually swim till about mid October. If I remember last year on Thanksgiving day it was hot and I was wearing a tank-top.

.... Oh so I had the wife today go to wal-mart and add 3.5 gallons of bleach to the pool. We'll see what happens in about 3 hours or so.

Get a drop based test kit .. The test strips are not accurate.

Everything since the shock of bleach ( 3.5 gallons). Really cleared up the pool.

The shallow end I can see the bottom and sides.

As for the deeper-end, it still kind of dark, however I can see the two main-drains; unlike before, which to me is an improvement.
