We recently moved to an older house with an existing pool. We swam at the end of the season last year and my daughter showed up with red blotchy eyes after swimming. I am figuring it's the chlorine. After reading about Baquacil, that is not a viable option. What other options can we take to minimize or forego chrlorine in the pool this season?

Someone mentioned a "frog system" Haven't found out too much about this and really don't want to go to a lot of expense, just want swimming to be pleasant and easy care for beginners.

thanks for any advice.
