Prior to doing test but after store gave me cya of 100 i added water to pool i actually didnt do it just to see if would help with cya but i had lowered to install thru wall skimmer quite a bit since not doing that i refilled pool back to normal level say probably increased 4 inches if looking at where level was on liner prior and after
Performed overnight ras dpd test here r my readings please advise
I had zero fc before adding chems and a ph 7.8 added 121oz bleach at 8.25
Waited thirty mins with filter on then performed test
Pm took 21 drops so 20x0.5=10 for fc
Pm took 1 drop so 1x0.5=0.5 for cc
Am test ( ive got to admit sun was already up for about 45 mins mins when got these reads
Am took 18 drops so 17x0.5= 8.5 fc
Am took no drops so cc is zero
i could not figure out the cya test im not really sure what u mean by cant see black dot...is it suppose to be completely unable to see or is it suppose to lighten to a sort of grey.
Ive done it three times and i always see the black dot so im thinking ive got a cya of zero.
Had to go to sun devil pool supply so i wanted to see what they got for cya ( i know everyone says dont let them test if u have the tf100. But i also know the cya is important i was bleachimg every night at 96 oz running filter 8 hrs and by am had zero fc.
So before i went messing around with this mucritic acid wanted to get some help on this cya readings
The pool store said my cya was 100. Maybe someone can help.me perform the test at home correctly because thats a huge diff. Maybe post a pic of what the black dot is suppose to look like while looking down tube for u to be able to take the reading. My black dot doesnt go away when i perform the test. Thanks for help on that
Ta is 12
Please advise on cya test and suggestions for what to add to get these numbers back more level. I will say my water is crystal clear and sparkling.
Thank you in advance
