Thank you everyone! I put a TON of bleach in it (figured it couldn't hurt), and it is now a beautiful shade of teal so it is getting bluer! So I definitely think it was the water and not the liner. Thank goodness. We had SO much rain last night, I just have to hope it does not overflow and cause more problems...ha. We both had to work this morning so did not have time to drain it, but it is almost to the top...ugh. So I shut pump off, and will drain some tonight, add more bleach, and hopefully we will be back in business on our way to a clear pool just in time for the beautiful sunny/hot weather coming up for this weekend! Thanks again!
