My CYA level checked last sunday was 40 and I am trying to raise it to 80. I have a SWG driving acid demand and keeping my TA on the higher side at 130.
I added enough CYA to bring the level to about 70 (according to the bottle). I bought a kit from tftestkits and the cya level today is 40 (twice) so I brought it to Leslie's and they also got 40. The guy said I need to wait a week before testing CYA adjustments. This doesn't make much sense to me.
Is there something that could be depleting my CYA? I want to be careful about adding more since from what I know getting the levels down requires draining water - a major pain in the neck for me.
Could there be something that masks a correct level? My current chemistry is :
TC 12 (I over did it after a big storm when TC went to near zero)
CC 0.5
ph 7.7
CH 220
TA 130
CYA 40
temp 78
Thanks for any assistance
