Test results in, needing advice

[Blou]

Results are:

• FC - 0
• PH - 8+ (5 drops so assuming I add the recommended 1.43 qt muriatic acid)
• TA - 130 ppm
• CH - 100 ppm
• CYA - dot never disappeared so I assume <30 ppm

• CC - Combined Chlorine 0

Water temp 75
Using Taylor 2006 kit

Would appreciate advice. Thank you!

 

[Mr Bruce]

pH first. Target 7.5 in case you overshoot. Get some CYA dissolving in a sock, use Pool Math to aim for 20. Add enough chlorine to get to 3 (Pool Math again).

How's the water look?

 

[Blou]

The water looks perfect. How do I determine how much CYA I have now if the test did not tell me?

 

[Mr Bruce]

If you never put a puck or shock or any solid chlorine you can assume 0.

 

[Blou]

Ok, Thank you! When do you recommend testing again?

If it is a fresh fill then it is 0 and I would add 30 ppm If not, then add 20 and see where you end up. More here on adding CYA and other chems, Pool School - Recommended Pool Chemicals
