Hello,
I have read here: oto-test-for-chlorine-i-am-quite-confused-help-t4994.html That you can indeed see what the free chlorine is.
Can some one or Jasonlion explain how you do that?
When I do the test with oto, when I put the 5 drops in the water you can see a color formation is this the free chlorine or is de color formation at the first drop the free chlorine or must I steer the solution first to see for some second the free chlorine?
Thanks,
JJ
