how to get metal out cheaply on fiberglass pool?
i have a white fiberglass pool. water is spotless all the way to the bottom. usually i can dump some stain away and it goes away. recently i did it and it got a worse brown looking stain than before. no i didn't add well water. is there a simple easy fix or will metal out do it. what works cheap? ph and alkili is fine. clorine maybe a bit low by the way. thanks
I'm talking about the brown metal stain on the walls of the pool.
