We had a new fiberglass pool installed and due to concrete dust and dirt etc getting into the pool it started growing algae shortly after, our PB came out and said he had a great new "natural" product that is a mineral cartridge that eliminates algae. I prefer natural treatments but like to investigate everything thoroughly before using it. He came over to check on our pool build and while he was over had apparently inserted the mineral cartridge into our system without asking. I asked why the water all of a sudden turned so blue and he let me know he had installed the cartridge which I was not too happy about. After he left I tried figuring out what he used (as he did not tell me) and figured out it was the poolrx black mineral cartridge. After reading the reviews and several posts here I am very unhappy that he put this cartridge in without my approval, now I am trying to figure out 2 days later (we did remove it after it was in for 2 days) how to get the copper/metals out of my pool water. A full drain and refill isn't possible, does anyone have any ideas on the quickest way to get this out of our water? Should we just continue to backwash and fill over and over? I am pretty frustrated with this as working with this guy had been one disaster after another. Our water was perfectly fine before minus the algae that was already remedied after we applied a shock treatment. Thanks!
