A neighbor set off a lot of fireworks July 4..a windy night..we ended up with a ton of debris in our pool! Within days our clear pool was green.we super shocked it. Took samples to the pool store several times..added ph . All levels are in the good range but the pool is as green as green can get. Tried metal remover..2 bottles. Was told not to vacuum until i can see the bottom..well its been 9 weeks! Did backwash after metals remover was added. scrubbed everything then added 3 bags shock and 3 more bags next day.still green.12500gallon pool.
