Ok so here's the situation....I have a CYA level of 250+. It has been this way for a while. I had a "professional" tell me "not to worry about it" a long time ago
I have not tested for copper yet, however since my 7 year olds blond hair is turning green and any white bathing suits are ending up greenish in color, I am certain I have a copper problem. I do not have a heater so I'm certain that some cheap liquid algaecide from Leslies is the culprit. I'm also aware that the reason I needed so much algaecide is because my CYA was so high so my FC couldn't do it's job.
I had a brown stain all over my liner. A neighbors pool guy came by and put a stain remover in that instantly began remove the stain, however within a few days it started coming back.
So just by reading about CYA here, this is what I need to confront first since it means I have to drain and fill, right? And if that is true, this should solve all my problems as long as I stay away from algaecides with copper, right?
If I am on the right track, I am wondering if I need to drain the entire pool to adjust the CYA or will draining half or more help lower it?
My feeling is that, since the stain remover helped temporarily, I should treat the stain again then immediately drain the pool and refill which should solve all my problems. Am I on the right track?
Any help from the experts here would be greatly appreciated.
Note: It is a small 8000 gallon inground so draining and filling isn't a terrible expense if this helps anyones recomendations.
