Thank you so much mbar & everyone for your help!

Just a couple more questions:

Where/how do I get the water tested for metals?

mbar, you said:

"You may have algae, because you need a minimum of 8ppms of chlorine in your pool at all times when you have a cya of 100 in order to have a really sanitized pool."

My CYA is 30. It's been ranging form 20 to 30 all summer. Did you think mine was 100?

Unfortunately, when I ordered more CYA from Ben earlier in the summer I thought I was getting two 4oz bottles but got two 2 oz bottles instead. Now I'm out and can't test it anymore. It took nearly 4 weeks to get the last order. Is there any other really quick source for CYA reagent? Our local pool stores just looked at me strangely when I asked if they carried it.

Mbar, you mentioned waiting until spring to clean up the stains. So it won't hurt it any if I close with the stains on the walls?

Thanks again for your continuing support and help. By the time I get this all figured out my kids will have kids of their own! (They're 11, 15 & 16 now)
