Goodmorning/night (I really don't know ) guys !!!
I'm back after a few days to share with you my last days test results, I tested water for chlorine, PH and CYA only
because I took for granted that there were not big changes in the other parameters :
22/05/2017 - FC=6 ppm, CC= 0,8 ppm, PH=7,4 , CYA<30 ppm
After initial addition of bleach i put also 3 small (20gr each for a total of 60gr) chlorine tabs
26/05/2017 - FC=13,5ppm, CC=0,5 ppm, PH=7,4, CYA= 25/30 ppm (after testing I added 25 ml by volume of CYA and a couple of inch of water )
Those 3 tabs raised FC levels over slamming level so I took off 2 tabs leaving just 1 tab, and left pool with no cover tarp for all the day.
27/05/2017 - FC=8,5 ppm, CC=0,5/0 ppm, PH= 7,4/7,5
FC drop down to a more reasonable level and I managed to get the sand filter working, was a night and day difference in flow rate.
28/05/2017 - FC=7,5 ppm, CC=0 ppm, PH= 7,4
I made the first bath.
I think I learned the first lesson :
With the pool covered for 24hours a day during the week I have a very low loss of chlorine, I still need to verify if one 20gr chlorine tab is enough or is still to much ...
I accidentally had the pool slammed for a couple of days, but soon after slamming the CC levels drop down to 0 or so.
What do you think about my experience ? Is there any hidden issue ?
As soon as I get good and stable FC readings I'll work on lowering TA, in the meanwhile I'will get ready for SWG !!!
