I did a SLAM about 2 weeks ago. And the pool cleared up perfectly.
Though, I had some issues. I wanted to use Bleach, so bought about 25 Liters of 12%. Or thats what I thought it was. Had to add it all to the pool, and still FC was only at about 3.5ppm... So, I had to add chlorine granules to get the FC up. But it worked out great
Because I currently live in Bali, Indonesia, I cant get my hand on any other chemicals (for CH, CYA, TA...), and apparently I'm stuck with using chlorine tabs and granule (as the bleach was old or too weak).
So, I've always had very low CYA. I fill the tube all the way up and can still see the black dot. But today I finally got a better reading, showing about 40ppm. Which is good.
But now have a question: Is this CYA coming just from the chlorine tabs? And not the granule?
I've only used about 3 tabs in the pool (about the size of a normal hockey puck), but could that alone have raised my CYA? If so, then I've reached my goal and can stop using the tabs.
My other question is; I want to SLAM again, as it seems these past few days it's getting cloudy again. See attached image.
Now, if the chlorine granule only adds to CH, then thats fine. I need more CH. But my tests shows CH is still too low, even after the last SLAM. So what else are in my chlorine granule? Do they put stabilizer in there too?
Just want to know if I can do another SLAM using my chlorine granule.
Todays test results are:
FC: 2 (i know, too low. I aim at 3, because I had 10-20 CYA before) Need to get it to about 5.
CYA: 40 (was 10-20 2-3 weeks ago)
