I am still fuming as I type this... A client of mine claims that my application of fertilizer turned their pool green. Apps have been performed on this property for over 1 year with no incidient. The turf area is more than 10 feet from the pool edge at any point. I have other clients where turf is much closer than that. They said a water sample showed Nitrogen content. Well so what, Nitrogen can be caused by rainfall can't it? Anyone ever heard of such? I think I could be the scapegoat here. And IF it was me, wouldn't the water sample also show sources of P and K? That might be my only defense.
