You need to shock your pool back up to 15. Also, run the pump 24/7 to let the filter trap the dead algae. Test your cl in the evening after sundown and then again in the morning within 2 hours of sunup and see if you are losing more than 1ppm of cl overnight. If not, your algae is dead and now it is time to be patient and let the filter do its job. (Don't test your pH when the chlorine is high, however, or you'll get a false high reading.)
Thanks! Just added the muratic acid and will retest in a bit.

I need some clarification on shocking the pool back up to 15. First off.....15 as in fifteen? Or 15 as in one point five? I bought some generic household bleach yesterday (6.x%). I had specifically asked Foxx pools several years ago if I could use bleach in vinyl pool and she said an emphatic "No!". I have a feeling that she was wrong. But before using, I just wanted to check to be sure. I can use in vinyl, right?

If so, how much bleach does one put in to raise the levels? I need someone to explain this to me like I'm six. With the salt generator, we usually don't have to shock and when we do I'll admit its usually involved hubby going out there and throwing in some shock willy-nilly. I would like to be pointed to some specifics.

Thanks again! You guys are very helpful!
