I have no idea. You don't list any FC level.

Sorry FCL 1.36, 1.90 TCL

Sorry FCL 1.36, 1.90 TCL

1.36 is way too low. You round CYA up, so if you look at the Chlorine CYA Chart, Chlorine / CYA Chart - Trouble Free Pool, at a CYA of 50, your absolute minimum FC is 4, and you should shoot for 6-8.

1.36 is not a result from a TF-100 test kit. What is the result using the TF-100

A lot of color blind people seem to be able to use the FAS-DPD test, have you tried it?

Your cya is high for a spa- only use liquid chlorine from here on out or you will run into sanitation problems as your cya will keep increasing.
As they said above u must maintain a higher fc level between 7-9 if your cya level is 60.
Also ta of 50 to 70 is ideal in order to keep ph rise to a minimum
your other post is inquiring about borates -
You should have your ta & ph in the ideal ranges before adding borates.
Here’s the guide w/all the recommended levels

I am also color blind and really it does not matter what color you see... Red, gray, blue... You count the drops till there is no color remaining> clear... Unless you see no color at all when you put the crystals in??
