Thanks! My pool looks gorgeous. I ended up empty my pool using the waste cycle while vacuuming always down to almost where the water was below the skimmer basket then re-filling pool putting hose on full blast and in the deep in so that it wiggled in water. I repeated this cycle while vacuuming and brushing sides for about week. (Happen to find a 6 ft wooden board in pool that was so soaked almost could not lift out). and of course added only bleach several times. Everything chemical wise is balanced. Thank you once again!
