Jandy Aqualink setup - I messed up and need some help here

[generessler]

With CC being 0 and no sun to eat up my existing chlorine, I should have more chlorine than what I started with since the SWG is running at 100%, correct?

I'm no chemist, but my understanding is that the CC test measures chloramines. That's what you get when chlorine binds urine, sweat, and certain oils. Chlorine killing algae doesn't necessarily make chloramines.

You can have algae with clear water and a CC of 0.

You do a Overnight Chlorine Loss Test yet?

Ok, turned off the cell at 9:30 pm last night and left the pump running all night.

Tested the water at 10:10pm:

TF-100
FC 8.5
CC 0

Test at 6:00 am:

FC 8.5
CC 0

No chlorine loss overnight. I had also tested this earlier in the afternoon using the TF-100:

TA = 50
CH = 250
CYA = 60

Do I need to bump up my CYA 20 or so points?

Got it.

And thanks for that PDA thread, its quite helpful.

Outdoors. No screen.

Then add 20ppm more CYA.
