Thank you all so much for your advice. I went to Home Depot and poured in the muratic acid into the return stream at the deep end.

Is there a way to know how high the cya levels really are? I am afraid that if they are really high it will cost a fortune in bleach, but on the other hand it costs $400 to drain and to fill it up again. I will order the test kit from your signature.

I have taken before pictures and will post the after ones when I get this cleared up.
