Re: C-y-a
update
+4lbs baking soda
+3lbs cya
+6 boxes of borax (24lbs I think)
+5 gal acid (borax & acid for borates)
+480 lbs salt
installed a SGS sg3000 swcg
As of 6:00 am this morning
fc=4.0, cc=0, ph=7.0, alk=70, cya=70, salt 4200
aerating water to raise ph as I am waiting on Borate test strips to be delivered. There is one strange thing my cya is testing at 60 to 70ppm but I have only added enough cya to raise to 40ppm. It was testing at zero 6 days after opening pool. First week of opening I didn't add anything but bleach. Water this morning is absolutely crystal clear (the addition of the borates WOW!)
