Jandy SWCG's "optimal" water conditions: why raise CYA?

[rpoldervaart]

SO HERE IS MY QUESTION TO ANY AND ALL POOL OWNERS WITH A SWCG THAT KEEP THEIR CYA AT 80 PPM AND THEIR CHLORINE AT 4.0 OR HIGHER, DO YOU EXPERIENCE OR GET COMPLAINTS ABOUT BURNING EYES? BE HONEST, BECAUSE THAT WAS MY EXPERIENCE.

I don't feel any burning. If my son swims in our pool, he'll have pretty clear eyes later on. He came home the other day after swimming in a public pool and his eyes were bright red. I have no idea what the chemicals were like in the public pool.

I'll second rpoldervaart's observation that a high CYA pool and free chlorine >= 4.0 doesn't lead to burning eyes. It's been a little over a week now since I upped our pool's CYA to 80, but in that time no one has complained about burning eyes. We swam after I used the Boost button on our SWCG, and so even swimming in a pool that had FC = 12.5 didn't lead to burning eyes or any eye irritation at all. I'd say we've had about 10 different people swimming in these conditions -- adults, teens, young children -- and not a problem at all.

But everyone's eyes are different, so what works for most people's eyes may not work for a few others.
