Would you add more CYA?

CYA: 30

I feel like I am having to constantly add liquid chlorine maybe twice a day to keep it a tad above my target (do not want it going near my minimum) We get a lot of sun (on sunny days of course). With a CYA of 30, and my other numbers as above, would it be best to bring my CYA up (once again) to closer to 40 at this point? When we first opened, I had 0 CYA, in which case I added enough to bring it up to 30 via sock method, and am wondering if the best thing to do at this point in order to hold my chlorine better throughout the day would be to add a bit more CYA, OR is my number of 30 a good number to hold at? Suggestions?

I would certainly consider raising it to 40ppm and see if that helps, maybe eventually up to 50ppm if you want. There is nothing special to do prior to adding more CYA.

How much are you adding? What target are you shooting for? 2-3ppm Chlorine loss per day is typical. So, for example, I would target 6, so if it falls by 3 over the day it is still at 3 and above minimum.


Don't forget, when you raise CYA your target FC goes up :lookhere: Chlorine CYA Chart
