Everywhere I look there's different rules for chlorine. Why?!

Here's the instructions on the back of a bottle of Walmart pool bleach.

1 to 3 ppm without stablizer but only 1 to 1.5 with stablizer? Wheres that come from?

That comes from outdated government recommendations that have not kept up with advancements in the science of pool care.

The pool industry has not accepted the science from 1973 to recognize the FC to CYA relationship. What we teach is backed by science and those that developed the methods are now working to teach and change the industry.
