It sure can if you don't have the CYA in there to buffer it.
Yours is still dissolving, and could take up to 3 days to register after it has dissolved completely.
I run my CYA at closer to 60 to help with loss to sunlight down here in the south.
I find that I use a bit less bleach to run the pool during the heat of Summer. I was running at 5ppm/day before I did that with my CYA.
