I have a very similar problem. And local pool stores no help. This Forum is the best place for good advice that actually works! Fiberglass pool, about 6000 gallons, cartridge filter. Opened pool, took a week to get water clear but it had green tint. Tested for metals, said none. Tried Leslie's stain remover and cleared the stains and the water as I watched. Two weeks later, some staining back and water a clear, light green again. I don't have the exact water chemistry, but it is about 7.2 pH and chlorine was high. I turned it up because I thought I had algae. Now lowering Chlorine to add more absorbic acid. What is the best sequestrants to use?
