Pebble Tech stains come and go in the exact same place

[julee d]

Pool was green, treated according to pool store recommendations, called for a lot of yellow treat, may have put a little extra, my pool has never looked this beautiful! A couple days later I noticed rows of green they do not brush off. I put a chlorine tab on it and it cleared that spot. So I shocked the pool with a granular shock. It is still there. I have seen these rows before and thought I was seeing things, but they are there. What does it mean if they come back in the same place? How do I keep them at bay/get rid of them?
I’m at a loss.
Look closely the rows are vertical in the image.

Yellow treat changes your pool from a chlorine pool into a bromine pool.
