Ok my husband and I are currently poolsitting for his Grandparents. Last night he turned on the hose to fill the pool for an hour. It was supposedly on a timer. WEEEEEEEEEEEELLLLLLLLLLLLLLLLLLL fast forward to this morning the timer never went off and the hose ran all night and now the pool looks like this .
Thinking it was copper due to the color we went to the pool store and got some "Metal Free". That was at 10:00 am today. It hasn't cleared up at all and it's 6:00 pm. Wondering if you all think it's copper or that it's something else. We tested both the pH and the alkalinity as of this morning and they were both normal.
Any and all help would be most appreciated. We know next to nothing about pools >_____________<
