FerriTabs ALWAYS did work. I was so glad to find them again. My pool water was saturated with copper from using copper algaecide which turned the water green along with staining my liner and steps. The FerriTabs did their job and removed the majority of the copper. I even bought two additional bottles for my neighbors who put in a new liner & had to fill their pool with well water. Within 24 hours, it removed all of the iron & other metals in their water and gave them a clear pool. Best product ever for removing metals from your pool water. They can keep the bottles of liquid “metal out” which never did work. Thanks for bringing this product back to the market.
