Don't know where else to post this.
I am in my 14th season as pool owner and 3rd season in BBB. Pool looks great, and I'm very satisfied with the chemical management of the pool. But, as my topic suggests, I have a new conundrum.
I started noticing this last season. My IG pool has an overflow spout that drains into the yard downhill about 15 ft. Starting from the exact location of the end of the drain pipe I have grass kill that extends 15 ft, over an area that is approximately 15'x6'. I also noticed significant yellowing of the grass in the area where I backwashed my filter this spring - so I am confident that something in my pool water is killing this section of grass in my yard. (The backwashed section of my yard recovered after about 10 days.)
Anyone know what combination of chemicals in BBB is killing the grass at the end of my overflow drain pipe?
