Hello, been a while but I have had this scenario happen the last few times I have tested.
In doing chlorine test, I add drops until water clears up. Then while I'm getting ready to do CC test I noticed the water (in the speed stir) slowly turns to a slight pink color (over the course of 30 seconds or so).
It takes about 4 more drops total to get the water to stay clear.
When I then do the CC test it stays clear at this point. As in zero CC
For sake of clarity, I initially get 20 drops to clear, then it turns pink. Then I add 2 drops and it turns clear, then slowly turns pink again . I add 2 more drops and it stays clear.
Water is about 63 degrees.
I have just recently noticed this slow change in color after initiallygoing clear.. Up until then once it turned clear it stayed clear.
Another note: (2nd guessing myself)When I run it through Spinlabs machine it says total ch of 13.xx but it also says CC of around 3. I did this test 3 times and it was pretty consistent.
I am not acting on the CC from Spinlabs because the TF100 test showed zero....after my above scenario played out. FWIW TF 100 results are all I EVER base any decions on.
Any thoughts?
Is color changing back simply because I had not completed the test?
One thing that concerns me is the spinlabs testing has never showed any CC before today.
