Free Chlorine assistance

[Pool3519]

Hi all!

I am new to the forums here and am looking to take control of my pool testing. I purchased the K2006 and I’m going though and testing all the chemicals. I have an inground pool with a gem finish that 13,265 gallons. My free chlorine reading was 6.6. The combined chlorine was between .3 and .4ppm. The CYA level is 40.

Should I act on the combined chlorine reading? Is it safe for the kids to swim at that reading? Thank you all

CC below 0.5ppm usually is not a problem.
As long as your water is clear enough to see the bottom, your pH is in the 7s and your FC is below SLAM level for your CYA (FC/CYA Levels) it is safe to swim.

If for no reason your CC gets above 0.5ppm than it is likely that you have a problem to address. CC is a byproduct of chlorine doing its job, it is responsible for the “pool smell” and can be a little hash on eyes, but not hazardous.

Thank you. All levels look good based on your feedback. There is no chlorine smell and pool water is crystal clear

about the only thing I would recommend for testing would be to use the 10ml instead of the 25ml level.. it uses less reagents and they will last longer..

With the Taylor K2006 kit, I used the drops which turned the water from pink to clear on the CC test. I know one drop (using the 25 ml test) represent .2PPM. One drop turned my water clear from pink immediately. However a few minutes later it turned pink again so I applied a second drop and the water in the vial turned clear again. A few minutes later the water started to turn pink. Am I to keep adding drops until it stays clear indefinitely or just until the water immediately turns clear? Thank you!

You stop when it goes clear. It will always go pink again if you wait.
