Using TFP test kit:
CYA holding steady at 50.
TA holding steady at 70.
PH holding steady at 7.5. (Only when I started with TFP have I EVER had and kept such a balance!)
At night, FC testing at 5ppm.
I lose 1 ppm overnight; 4 ppm during day.
So, based on pool calculator, using 12.5% bleach (Vertex) to bump overnight to 10 ppm - I am adding 8.5+ cups of bleach per night! This seems like an extraordinary amount of bleach, particularly at 12.5% chlorine! Is it because our temps are so high? Getting 8-10 hours of sunlight on pool? Is the Vertex the problem? I do get it a my local pool store - with discount, it runs cheaper than bleach.
My husband is questioning the cost effectiveness of this method vs. tablets, even though I remind him about having to dump so much water due to increased CYA with tablets. I honestly don't remember how much those tablets cost though, but I do know I don't like having to drain so much water out of the pool when CYA gets high!
Thoughts on the amount of bleach I am using???
