Stabilizer ?

[AnnaK]

My TC is 11 or 16 unsure how you calculate this

Total Chlorine = Free Chlorine + Combined Chlorine

An FAS-DPD type test kit can measure FC at concentrations far above 5 ppm which is the value at which most other tests quit. A TC of 11 (or 16) means your CC is 7 (or 11) which is an indicator that the chlorine you're adding is working on something in your water. I am not familiar with the test kits you use, don't know their range, and am somewhat concerned that your numbers may not be accurate.

In my opinion, there's little sense at throwing a flocculant at the water until the FC holds steady but without being able to test for the high concentration of FC needed for the amount of CYA we're all just sort of working in the dark, guessing at why your water remains cloudy.

This thread started with TA "around 30". How did it get to 140?
You added 3.75 pounds of stabilizer which would have increased CYA by ~ 12 ppm. How did it get to 70 ?

I'm having a problem with the testing and the numbers.
