Cya test

[Jsf721]

Is this accurate if it’s overcast out. Getting pool ready for a fun busy weekend with lots of friends.

Plan on getting out to test mid day Friday. Weather calls overcast /rain.

Thanks

Yes, even overcast is ok. Best if you are outdoors, even overcast is better than indoors.

Remember, FC is safe, even up to SLAM level. If you have any question about CYA level, raise your FC above target range for your CYA, to protect from any issue due to FC demand (lots of swimmers etc.)

Your CYA tested 70, 3 days ago...it will not change in 3 days. FC up to 28 is perfectly safe for people and pool.

Best is if the sun is at your back when testing.
