I am struggling to figure out what the best CYA level is for my pool, based on my current conditions.
As you can see from my log, I got CYA to 50 on 6/19 (after having a staring point of 30 and adding stabilizer)....then it raised to 60 by 7/4 (I did not not do anything raise it 60). Now today on 7/17, when I tested it is 40 (again, I did not do anything to drop it to 40).
The last week have had RECORD heat and our pool is about 86-88 degrees. Could that cause the sudden and large drop of CYA? Is it typical for CYA to change alot in the summer under these intense desert conditions? Typically, we are burning through 4-6 ppm of chlorine per day (which based on FULL SUN, heat and everything else sounds within range?)
I have stabilizer on hand and have the ability to raise the CYA...but what should I raise it to? I have read some people maintain a CYA of 70-80 when they are in desert places during the summer. But, I am getting a bit confused reading all the various responses.
As a side note...we are going away this week for 4 days (Friday-Monday)...so I plan to take the pool to shock level and add 4 pucks (that go in a holder that sinks to the bottom) and take Ph to 7.2. So, knowing what my target CYA level will be will be very helpful in this process
Thank you foray help you can provide
BONUS Question: Most people say that a pool will settle/stabilize Ph around 7.6-7.8. Problem is, my CH is around 850...so,that puts my CSI at .6+. I also noticed that if I keep my Ph higher (and thus don't add as much MA as frequently) my TA starts rising. So, based on all of the above conditions...I think it is a better course of action for my pool is to aim for ph 7.2-7.4 even though that means me adding more MA and more frequently. That way it keeps my TA and my CSI at a better spot.
