Yes, so my CYA is below 20
This is my first time testing...my god I think it took me 30 minutes reading it word for word to make sure I didn't do anything wrong.
So, do you guys need the results of the Fas-dpd also?
I also just went ahead and bought the speedstir also I have it now...should I test the Fas-dpd with this or do it like the youtube video shows?
Update...I just went ahead and did the Fas-dpd in the speedstir and the Result is 1
What do I do now?
The pH is right on the money, so you start the
SLAM. Just follow the directions.
If I was there in person, I'd use
poolmath to figure out how much bleach I need to get to 10 (That's SLAM level for <20 CYA) and add it.
psst it's 2 full jugs of 8.25% clorox Then I'd weigh out enough CYA to get to about 25, just in case there's some left in there but too low to read.
psst 4 lbs of stabilizer granules will do it. I'd put that in a sock or nylon and set it in the skimmer and start brushing and vacuuming. After an hour since the last bleach addition, I'd take another FC & CC reading with the FAS-DPD test and add enough bleach to get FC back up to 10 and finish my brushing and vacuuming. And if there's still time before bed, I'd test it and take it to 10 FC again.
Tomorrow morning, I'd take a look at the filter pressure to be sure it wasn't loading up and needing a backwash and deal with that first if necessary Then I'd assume the CYA was dissolving and start using 12 as the FC target from then on out. And as often as I was able, I'd test FC and raise it back up to 12.
I'd also take a picture to post so everyone can watch the progress.
But that's just me.
