Free Chlorine vs. Total Chlorine adjusting

[Truckman]

It is the reading with OTO. What is really confusing is the pool looks much, much better today and the Chlorine reading is lower today than it was
yesterday. It don't see any algae or residue, its just cloudy and seems to be getting better, but this is with the lower chlorine levels. I just added another
2 gallons of bleach about an hour ago so I'll see what it looks like in the
morning and do another test.

So you're saying that the CYA residue is causing th cloudiness and not
algae.
