thanks to both of you.
i really do have POP
i know i ask too many questions, but i just want to make sure i understand
and follow what you guys say.
when i encounter a problem, i just ask you guys then wait for you to tell me what to do. pool has cleared more this evening. i see that i am going to need help with the stains, but i'll ask you how to take care of that once i get it cleared up.
