Cyanuric acid missing

[smileitsachoice]

I have started up my pool for the spring. Opened to a green mess. After about 70 gals of bleach (30k gal + vinyl in ground), I have apparently held chlorine overnight. My question is I tested at zero cya at opening (I am sure it was eaten by bact.). Normally I keep at 50+ ppm due to living in the deep south. I have started adding cya with 2 socks with 3 lbs each at each skimmer entrance. My question is (finally I know) Is it ok to add bleach in the deep end with the cya at the sides? Oh yea ph is 8 to 8.5, alk. is 90. Thanks, been using the bbb method for 3 seasons and it was the best thing I have every done for my pool.

Hi, glad to see you back!! Yes, it's fine to add bleach at the deep end with the CYA at the sides, just don't put them into direct contact with each other. You need to get the pH down below 8, though. Low chlorine, low CYA and high pH are ideal conditions to use trichlor, if you're tired of hauling bleach

yes good idea, Everybody at Sams probably thinks I am building bombs or something

Janet,
I just checked my ph and is was probably over 8. I went ahead and added some acid, how long do you think I need to wait to retest. Also I was going to retest about dark and add bleach to get me to about 8 or 9 ppm. Does this seem like a good idea.

I'm not Janet but ............You can retest pH after 3 hours or so. Give the acid plenty of time to mix in well. Yes to adding more bleach this evening.

Watermom,
Sorry I thought Janet had answered my first question but thanks for the reply. Will retest tonight.
Thanks
