Quick question on SLAM

FC - 10
TC - 10
CC - .12
PH - 7.2
CYA - 50
It looks like the app is telling me I should be at 20 on total chlorine and to add 3 gallons and a quart of 10% bleach. I'm not a premium user so I can't log. My question is how do I save my current readings on the app, and does this look right to the experts?

Looks right. A subscription to the app is money well spent.

Note that TC is just a math formula which is TC=FC+CC

so it’s not possible for the above reading to be accurate (unless there’s some rounding off going on) Technically your TC would be 10.12ppm.

For future reference you can ignore TC since it’s not a measure of anything which the FC and CC don’t already provide.

Hey neighbor
The app overview will store your last result- if you are not a subscriber then your next log will replace it.
It’s $8/yr & well worth all the convenience it provides.
Also once you begin the SLAM Process you only need to test fc & cc. Remember the more often you test & replenish fc to slam level the faster your slam will go
Good luck SLAM ON

So the SLAM went good, water clear. My problem is that the free chlorine is staying at 27. There has been no chlorine source for 2 days, Alkalinity around 70, PH 7.8 (but not sure if accurate at this high level of FC), don't know CYA because I ran out of the reagent but it was 50 at last test. I drained about 6 inches last night and refilled with little to no results. If I follow Pool School and go sodium thiosulfate, where is the best place to get locally?

Sun on the pool surface will consume some FC. No need to mess with chemicals. Let it naturally fall.

Slam fc level for a cya of 50 is 20ppm - why is fc so high?
We don’t recommend going above slam level as it just wastes chlorine & can cause damage to surfaces, equipment, & swimmers. It doesn’t make the SLAM Process end sooner. The sun will lower it over time. We have some sunny hot days ahead. Are u sure your swg is off?
