Members of the Port Orange Family YMCA who have had to wait to take a dip in the clear blue waters of the center's pool will likely have to wait longer — at least another week, a spokesperson said.The pool located at 4701 City Center Circle was forced to close July 5 when the clarity of the pool's water became a concern, according to Port Orange Parks and Recreation Director Susan Lovello.While originally it was thought to be an issue with the chemical components in the pool, Lovello said, the problem was eventually found to be a mechanical issue with the sand filtering system.
