I just received my TFP kit. I used it for the first time today.
My pool has been open for 5 days. Today is the first day I tested it. It's a 21000 gal gunite salt water pool. I live in PA. I'm trying to follow the "Water Balance for SWGs" post but have a few questions related to salt and CYA below since those seem to be the first things to get into balance.
Here are my less than stellar pool results:
pH > 8.2
CH = 350
TA = 150-160
FC = 3
TC = 4
CYA <= 20
1. I've been told to wait for about a month for it to get warmer before adding stabilizer. Should I do this? CYA =20.
2. I replaced my salt cell last year and my Hayward electronic unit says salt = 2900 but when using AquaChek salt test strip it was around 2500. Which should I rely on? When closing last year I know that it was over 3200 and no salt was added at opening.
3. I added 1/2 gal of muriatic acid to lower pH and hopefully lower TA too since it was so high.
Finally, what should I do first? I was thinking of adding 1/2 to 1 bag of salt. Then trying to focus on pH. How often do I test pH - when it's high? and how often when I finally get it in range? pH seems to be the one element I have a hard time controlling.
Note: my pool is somewhat clean but still has some tree "helicopters" and dirt on the bottom. My Polaris robot is in the shop and i didn't get it to completely clean the bottom and sides after opening before it broke. I have brushed and used the net but can only get the bottom so clean.
Thanks in advance.
