Thank you for the reply.
36 oz of Metal Out. (32 oz / 10,0000= gal, I have 12,000 gal)
The metal out is just to stop the oxidizing of the iron before adding chlorine for the fist time of the year.

Apologies for the big image sizes.

1 week ago. Nothing added, this was the winter condition. pH was 8.0+






Now, a week later with 36 oz Metal Out, muriatic acid (pH = 6.8) and dichlor.






My current test are in yellow results so far. (Ignore the 2013 entries.)
