Chloramines!!

[timmco]

Recently, everyone's eyes are getting irritated after swimming. I read that it could be due to chloramines. How do I fix this?
Water is clear, chemicals are balanced.

Did you test the level CC? Are you maintaining your FC level based on the FC/CYA Levels?

pH can also be an eye irritant. Do you maintain your pH in the 7's?

Your Poolmath data shows some large variations to pH.

I am maintaining my FC/CYA level. How do I test for CC?

The FAS-DPD test. After doing the FC test, you add 5 drops of R0003 and if pink, use the R0871 to clear. Each drop is 0.5 ppm CC.

I am very low on chlorine today. I forgot to add some yesterday (I worked all day). So I am definitely adding more tonight.
I tested for CC. When I added the R0003 I dont think it turned pink, if it did it was a VERY slight hue.
However, after swimming today, everyone's eyes were irritated.

Hard to say. Eye irritation can be low pH or CC. Or they are rubbing them too much. Or they are using sunscreen and it is getting in their eyes.

It must be CC. So let's say I have .5. What would I have to do to lower it?

.5 is nothing.

Chloramines are a waste product from oxidation. UV breaks it down the rest of the way quickly.

What is your pH?
