I am having difficulty keeping the water clear and "blue". Over the past few weeks I have added 2 bottles of HASA Super Stain Out which cleared up the pool for a few days at the time until more chlorine was added. When more chlorine was added the pool turned back with a tint of green. What should I do to ensure that the water doesn't turn back to green?
added: 2 HASA super stain out, CuLator metal eliminator
