Opened pool to a green swamp!
Ran my first set of tests on March 14th and got these numbers:
ph - SUPER hot pink (off the charts)
Alk - 80
Added what I had left of my muriatic acid from last summer (about 1/2 a jug)--retested, and ph was STILL super HOT pink. Decided to shock pool to remove algae, and keep shock level (FC) at about 17...pool went from green to turquoise.
Ran another set of tests TODAY, March 16th and got these numbers:
FC - 5
CC - 1.5
TC - 6.5
CYA - 40
ALK - 60
Calcium Hardness - 90
ph - STILL very hot pink.
**I let my FC level drop down from 17 only to test the PH real quick to see where it was. ALSO, I have SCALE on the sides of my liner. It's horrible, so I know my pH is WAY off.
**I assume I need to tackle the PH first, and then bring my pool back up to shock level, right? (I bought 2 jugs of acid just a few moments ago)...
What's throwing me off is my LOW Alkalinity?? Do I get my pH down to about 7.0 (to get rid of the scale), and then raise the Alkalinity with Baking Soda (which will also RAISE my pH though)?
**I also need to get my pool back up to shock level to kill the algae/combined chlorine, but I assume I need to tackle the pH and alkalinity first.
Any suggestions on what steps to take (and in what order) would be greatly appreciated.
I am very embarrassed that my pH is so HIGH. I always take good care of the pool in the summer, but let it go all winter without adding ANYTHING to it (so this is all totally my fault).
Thanks for any help you all can give me.
(edited to change borax to baking soda... )
