Hi..I hope someone can help me. One day after swimming, I noticed blue water rinsing out of my hair. The shampoo bubbles were even blue. The Q-tip I used to dry my ears left the swab blue. I called my pool guy as he had serviced the pool a couple of days prior to this incident. The service was really normal he said...nothing odd, nothing new during the service. He was baffled. My husband swam the day after I did and he too found his beard had a tinge of blue and hair had a green tinge. When my pool guy showed up, he found an ink pen in the pump basket. He brought it to my attention thinking this was the reason for the blue water in my ears and in my hair. I then remembered my cousin's puppy fell in the pool and she jumped in the pool with her work uniform on to grab the pup. An ink pen had been in her pocket. the pool guy didn't notice it in the pool when he was vac'ing but that's the only way it could of bypassed a skimmer basket to get to the pump basket. so the ink from this pen has probed to be the culprit...it is still haunting us and turning our hair blue and green. It's been since October, and the pool service has flocked a few times and cleans the filter each week and we cannot get the blue ink out of our crystal clear water. Has anyone ever had this problem and/or does anyone have any suggestions, guidance, or solutions for me? It is an in-ground fiberglass pool. 3-8 ft deep. no staining from the ink on the fiberglass. Ive wondered if I should drain half of the water out and refill every few weeks? I would have thought by now, the ink would be so diluted that we would no longer have this problem...unfortunately that is not the case.
