Pool Water Turned Green After Adding Shock

It's safe now. I just finished a new cut and paste sticky on the topic.

================================================== ==========

+ Over the 15 years PoolSolutions and the PoolForum have been active, we've gradually accumulated evidence, and gained confidence, that concerns about swimming in high chlorine levels completely without foundation, and that the EPA's rule for chlorine bucket labels, of "no swimming till chlorine levels fall below 3 ppm", is simply floating in the air. But, it was not till this year, 2012, that we were able to put the last nail in that coffin.

It turns our that dermatologists have been using 50 - 100 ppm "bleach baths" (search Google for it!) to treat a variety of skin conditions and infections, in both adult and pediatric patients. This treatment is still an element of recommended dermatological practice. A 50 ppm chlorine level in a tub with NO stabilizer, is equivalent to a 150 ppm OR HIGHER chlorine level in a stabilized pool. In most home pools, CYA levels range from 20 - 100 ppm.

Two cautions however: bleach baths don't involve opening your eyes underwater. And, patients being treated with bleach baths don't wear swimsuits! People, generally are FAR more chlorine tolerant than swimwear, and human eyes are more senstive to chlorine, than the rest of your body.

So, while you can safely SWIM at 50 ppm even with CYA = 0 ppm, you wouldn't want to wear a swimsuit when you did, or open your eyes underwater. With CYA = 100 ppm, it's a different story. I'm currently operating a large commercial pool at CYA = 80 - 120 ppm, and FC = 15 - 30 ppm. There have been NO complaints or evidence of either irritation OR swimwear damage.

Thanks brotha...you're a Godsend!

We're jumping in tonight!
