We just put up and filled our pool this past Saturday. I opened my 3rd large bottle of bleach tonight. I feel like I'm having to add quite a bit each night to keep my FC levels up. Here's what I'm looking at since last night...
Wed PM -- Th AM -- PM
FC - 10 --- 9.5 --- 4
CC - .5 --- 0 --- 0
pH - 7.5 --- 7.5 ---7.5
TA - 340 - didn't retest
CH - 60 - didn't retest
CYA - 30 - didn't retest - consistent reading for previous 48hrs
Temps over 100 today. Water temp about 92. Pool gets about 10-11 hours of sun. Water is clear and sparkley...in my opinion.
Does a 5.5ppm drop in FC seem normal during the day? If so, I would have to add enough bleach to raise my FC to 10ppm each night so it doesn't drop below my target (4ppm) by the following evening. I know 2ppm is my minimum but my best bet would be to keep it closer to my target right? Before last night I was raising my FC to 6ppm each night but would end up well under my target by the end of the next day. This disproves my theory that I'm adding too much and it's burning faster...right? Right? lol And I passed the overnight test by only dropping .5ppm right? Help please!! Do I need to increase my CYA? And adjust my FC target accordingly? That's what is floating around in my head but I'm too new to be making decisions like this on my own. lol
I added enough bleach to get me back up to 6ppm for the night since I won't be going back out. And I'll be home all day tomorrow to do what I need to with it.
