0 CYA

[brasilmom]

Greetings,

Summer is upon us and I have been taking care of our pool so we can all enjoy a good season.

I shocked the pool on June 13th and got it to a level of 30ppm. Our weather has been rather dry until last night, so I added water to the pool a few days ago, hence the shocking.

I just tested the pool this morning and I have 0 FC. It did not even turn slightly pink when added the reagent. I tested the CYA and it was clear as day light. So, I need to add some of Cyanuric acid and then chlorine.

Question: I checked the calculator and it says to add about 275oz of acid. I also need to add chlorine. In which order shall I add then? Is it ok to add then both in the same day/time?

PH is a bit higher, but I believe that the acid will lower it, correct?

The water is not cloudy or anything.

Thanks. Be well

Miriam

Not at literally the same moment, but fine to add them a few minutes apart.

Thanks. I have about 6lbs of acid and probably will need to use it all. Should I dilute in a bucket first or add it directly to the pool? It has been a long time since I last add that.

Add muriatic acid by pouring it slowly in front of a return jet while the pump is running. Add cyanuric acid by putting it in a sock and putting the sock in the skimmer.
