Hola! I have question concerning the appropriate CYA level for a SWG. The TFP Chlorine/CYA chart indicates that an appropriate level is is 60-80, however, 60 is not recommend. I was just curious why that's the case? Should I target a CYA level of 70 and FC of 5?

That would be fine. The lower the cya level the harder the swg has to work to maintain chlorine due to losses to the Sun.

Ok, that makes sense. Now if only I can get an accurate CYA reading. I swear I can see that dot (lol). I'm assuming it's 60 but I'm afraid to add more in case it's 70. It wasn't hard to tell when it was only 30 but I've been slowly bringing it up.
