This is the first time I have had a pool. We have just put up a pool filled it from the hose about 2 weeks ago. Brought water to our local pool store. Added what they told me to add to get the PH, TA, CH, CYA & algicide where they said it should be. They talked me into the Susatin pool chemical so right now that is what I am using. Since then I have been reading pool forums like crazy. I added the shock tablets last night. I received my TF-100 test kit today & these are my first readings this morning.
FC 19
CC 4.5
PH 7.6
TA 130
CH 200
CYA 20
Tested Chlorine again 4 hours later:
FC 15
CC 6

I also went to my local pool store their computer is saying
TC 7.8
FC 7.8
PH 7.8
TA 175
CH 250
CYA 40

After reading through websites it seems like the BBB method is the way to go but since I have already bought the Sustain system I want to finish them before I switch since I just don't have the money to through out. Any advice would be great. Also, where should me chlorine levels be & how high is to high to swim? Pool store says its OK to swim. I am just confused.
