Hello everyone,
I have a 1 year old San Juan 10k fiberglass pool that the installer left with metal stains. I was finally able to get rid of most of them over the last 2 weeks and I'd like to get my water balanced to where it needs to be. As of 3 hours ago, here are my levels:
FC - 1.8 - I got it back up to 2 after adding liquid chlorine a bit at a time for 10 days after using ascorbic acid. And now I've just turned on the SWG to 8% to keep it around 1.5-2.
CC - 0.0
PH - 7.4
TA - 65ish
CH - 190ish
CYA - 35ish (if I squint real hard I can still see the darn dot)
Water temp 55 degrees at the moment. (I'm in NE FL and it's been chilly lately).
I have not tested my tap water but I've only added 2 inches once 6 months ago because of all the rain we get. Instead, I drain 2-3 inches once a month.
Here are my questions:
1. The San Juan book and the their rep says that the TA should be 125-150. But everything I have read online including here mentions to keep fiberglass pools in the 60 to 90 range. Which one is it?
2. The SWG and liquid chlorine raise the PH which I have to reduce with muriatic acid which then lowers the TA which I then have to raise with baking soda which still raises the PH some. But this is a never ending cycle. Is there a magical way to end this cycle?
3. The TFP's Recommended Levels are 350-550 for CH and 70-80 for CYA - but again this goes against what my manufacturer recommends which is 175-225 for CH and 30-40 for CYA which I'm perfectly in the middle of. Where should I be?
Thank you for all your help. My profile lists all my equipment and I am trying my best to learn and do the right thing. Thank you!
