I’m sure this isn’t a common issue, but for ones with sons at home? May be more common than I realize, so figured I would post here.
This summer, I took over care of my SWG pool from former pool service co. For past couple years, would see a few dime sized brown spots at bottom, around edges of the pool. I assumed they were from pool guys dumping in chemicals and not brushing around after. I was wrong- sorry for blaming you for them, pool guys! (However, have found many other issues that were missteps on their part… fixed w the info here. But, I digress)
But I as continuing to find new additional brown spots- searched here for what it was and what to do.
Got Vit C tablets, cut in half and placed on some of the spots- took them right off… *then* while pushing tablets into place w my foot, standing in my spa? Hmmm? Are those little rocks down there? Nope! BBs. From our Red Ryder BB gun
Misfires/bad aiming by my older son while in the back yard- sank to the bottom and made the rust/iron spots (guessing also that “copper” BBs aren’t really copper since Vit C removed them)
But, for anyone w boys w a BB gun, seeing spots? May need to investigate as it could be the same for you, too!
