After checking my pool water and finding extremely high CYA levels I decided to just start from zero with new city water.
5/6/2016 5/10/2016 FC (Cl-Br) 0 3 - 6 TC 0 3 - 6 CC 0 0 pH 8 7.4~7.5 Acid Demand 2 NA Base Demand NA NA Total Alkalinity (ppm) 140 120 Calcium Hardness (ppm) 90 110 Cyanuric Acid 0 0
This is what I have as of today. I added some Muriatic acid on May 6th to lower the pH and Alkalinity levels.
I also added some shock to the pool since I started to see signs of algae on the bottom of the pool.
What should I do next?
Can I start adding Cyanuric Acid (staibilizer) or should I get the Calcium Hardness under control. I also feel inclined to add bleach so that I may begin to increase the chlorine levels.
