Following advice from szampino,waterbear and other's the stain is gone.I'm in process of bringing the chlorine level back up to the proper level. The chem levels at this time are ; FC .5,CC 0,PH 7.0 ,Alk 100,CH 90 can't do the CYA,ran out of the reagent. I have a question about the copper reading which is .05. When the copper is in solution using (metal free) ,the test kit doen't appear to read it. Is the copper being removed or is the test kit not reading it?
Many thanks to all that helped! I just hope it stays the way it is. If it starts to come back again any suggestion on what to do would be appreciated. I can post a more detailed procedure of what I did, if any one is interested.
