I'm a new pool owner and am hoping to get some advice on adjusting the CYA level in our pool. We just had it replastered and it was filled about three days ago. The builder also added a bottle of Startup Tec (http://www.mcgrayel.com/startuptec.html) The builder has been helping with the startup but I'm taking over the chemistry starting today. I just tested my water this morning and this is what I've got:
FC = 1 ppm
CC = 1 ppm
TC = 2ppm
TA = 40
CH = 275 ppm
PH = >8.2
First of all, I clearly need to add some FC (I'm doing bleach) today and also some muriatic acid, right?
My other question is on the CYA level. My builder added two pounds of shock two days ago (this stuff from Leslie's, specifically - http://tinyurl.com/pv7odq3). In doing some reading here, it sounds like shock is not preferred for the TFP method and can raise CYA levels as a side effect. So here's my question - how much CYA should I add now (I've got some HTH brand stabilizer/conditioner)? Should I be worried that any CYA introduced via the two pounds of shock a couple of days ago isn't registering yet, and so if I add a full CYA amount based on the size of my pool I could end up with too much?
Thanks for any help!
