First time pool owner here so bare with me while I try to get through this. We opened the pool for the season approximately two weeks ago - it's inground, vinyl and approximately 19500 galloons. I expected it to look a lot worse.. once they were done suctioning the green gunk off the liner, it actually looked pretty good. We took a sample to our local pool supply store and were told that we needed to get our PH and TA in check before tackling the chlorine which was virtually nonexistent. We finally got those in check so we started working on chlorine. It wasn't holding so we were told we needed to "shock" it. Put the recommended granules in and chlorine would rise but would eventually fall back to 0. Today's reading is as follows:
FC - 0
TC - 0
CH - 250
CYA - 99
TA - 100
PH - 7.2
PHO - 300
Came across this board and realized that we should probably be shocking with bleach at this point. I plugged the numbers into the pool calculator and it looks like I am looking for a shock level of 25 and in order to get this, I need to add about 950oz of bleach. Is this right???? Do I do it all at once or over time?? Seems like a very high amount and I don't want to ruin my liner. Are we on the right track?
