Do I need to SLAM

Envieddesigns · Apr 5, 2022

Would I need to do another SLAM being that 3 days ago my chlorine level went to zero. I did a motor replacement over the weekend and ran into other issues that left me without testing/ filtration for 2 days.

As of yesterday I was back up and running at 7pm. Water is nice and clear.
Tested levels yesterday were
FC 1.5
CC 0
CYA 60
Added 1 gal of liquid Chlorine per the app
Tested at 9pm
FC 10
CC 0.5

Tested 11pm
FC 8.5
CC 0

Tested Today 9am before work
FC 9
CC 0
Tested 530pm
FC 4.5
CC 0
Added Liq. Chl.
Todays we had no sun so assuming by that drop that I still need to kill off something? Originally I passed the SLAM overnight test on 3/23.

Water is crystal clear and you show a 0 FC drop in an OCLT (pump was run all night, correct,?). No reason to follow the SLAM Process if true.

I'd do an OCLT to be sure all is right if you're in doubt.

Correct, only thing I noticed when I brushed today is like a light dirt come up off the floors but Im also over due for a vacuum. Last was 3/23.

Monitor. But sounds like things are in good shape.

No sun and a loss of 4.5 seems a bit much too me.

Retested I’m at 8.5 FC now after the dose. I am going to test again every hrs before I hit the sack and see.

So I tested twice last night before bed
My last reading I got an FC of 10
This morning FC of 10.5
Also we are currently having heavy rains since early this AM. I didn’t check my PH, is it safe to say that it’s not worth checking during a rain storm since it affects it?

Your FC going up overnight indicates someone is adding chlorine to the pool or testing error (or not waiting long enough to test after adding chlorine)

You’ll need to figure out what’s going on to know how to correct.
