Kids eyes are irritated since new SWG

[Catchyduck]

I got my pool about 5 yrs ago. I immediately started treating my pool based on the advice from this site. 3 months ago I bit the bullet and got an aqua right 900 SWG. Since then my kids eyes have been very irritated. This was never a problem before. I can't figure out what changed? Any help would be greatly appreciated.
FC 9
CC 0.5 (I'm hoping this is the cause and shocking will solve)
CYA 50
TA 80
CH 200
PH 7.8
Salt 3500
Apx 20,000 gallons
Vinyl

Welcome to TFP!!

When converting to a SWCG pool you should be using a different table on the [FC/CYA][/FC/CYA]

If you look at that the minimum CYA for a SWCG pool is 60, and even at CYA 60 the target FC is 4. Wde actually recommend CYA to be 70-80. Pool School - Recommended Levels

So, your FC is way high for your CYA. That is my guess as to the problem

Thanks Tim. I'm new to the SWG. I'll up the CYA and lower the salt setting. the pool calculator said my CSI was -0.2ish so I figured I was good? Thanks for the quick response
