Hello all -
Hope to get some advice here.
Heres the last several weeks . . . I was on vacation for three weeks and came home to some brown mold (brown-yellowish dots on the upper sides of the pool - cc 0.5). Killed the brown mold with high shock for 3-4 days, 24hr running of the pump (Bleach +15ppm @ CYA 40). Checked all the other numbers and everything fine. I have been back from vacation last two weeks and have had no time to really keep an eye on the pool except to keep the chlorine level between 3-5ppm with bleach (I add one jug every 2-3 dyas). Last time I checked the PH it was high (~1 week ago) and I lowered it to about 7.2 with acid (checked this with test kit aftwerward). So yesterday, I saw some small patchs of the brown mold and I checked the FC and it was less then 1ppm and the PH was off the scale (8.2+). I added in muriatic acid (enough to bring it down to around 7.6 and I added in 6 jugs of Bleach (15ppm). So here are my numbers as of this am
FC - 15ppm
CC - >0.5
PH- >8.2 (This seems to high!!!! As I just added muriatic acid yesterday @ 2 liters)
ALK - 90
CAL - 200
CYA - 30-40
SALT - 3300
I have IG cement pool with SWG (30K).
My question is will the high chlorine be giving me a false PH reading?
Your thoughts appreciated.
Thanks
