i used my home tester kit my pool is really bad green i added 6 jugs of chlorine and 2 jugs of acid.. with in a week time cuz usually if my pool turns green i add a few jugs of chlorine and a little acid and it clears up t his time its not working and so i added more so when i did the home test kit it shows now that i need to add phosphates soo whats that mean like did i put tup much of chlorine and acid in there.. or is that just what my pool is lacking so thats why it turns green so often..
