I am going to close the pool on Thursday, so I started taking ladders and handrails off today. Add bleach to bring it up to slam level, and will let it drift down before closing and covering. All other numbers looked very good.
This is a picture of the inside of the ladder when I took it off today. I didn't see anything else that looked funny, but I am not sure if this is some sort of algae, of maybe a salt residue. Any thoughts?
