unklebuk--The result that would concern me the most is the chlorine level of 1 ppm being WAYYYY too low for a CYA of 150. For a CYA that high, you should be keeping your chlorine between 8-15 ppm at ALL times, otherwise you're inviting the algae back.

What is concerning you? Also, if you would please start a new thread instead of adding into the bottom of this one if you're needing help, it would help keep things easier. You would get more views and responses, and it will be easier to keep the two pools and their respective problems straight....

Thanks!
