Greetings once again TFP!
Just opened my pool today. Here are my numbers. I would love feedback on what to do next.
FC - 0
CC - 0
pH - <6.8
TA - 40
CH - 50
CYA - 0 (I realize it's probably not truly 0, but when I did the test it never clouded up)
I was unsure what to tackle first considering everything seems to need work. After reading a good number of posts I went with getting my pH up. Since I don't really know it's exact number (other than <6.8) I took a guess at about 6.6ish (hoping not to over shoot.. it could be less than that) and added 100oz by volume Borax, as per the Pool Calculator, to get it to 7.5. The PC also states that by doing this my TA will rise to a healthy 56, so that's good.
First question: how long should I wait to retest the pH? I've read 30 minutes but would like to confirm.
Second question: should I get my CYA up to about 30 - 40 BEFORE shocking? Or can these be done at the same time? (i.e. put in enough stabilizer to get CYA to 30 and, at the same time, enter enough bleach to shock as if the CYA was already at 30).
It's always great to have the support of the TFP crew!
