You'll find it harder and harder to keep your mouth closed when listening to the pool store--the last time I had to go wait a few minutes in line to pick up my Polaris from repair, I actually had a headache before I left from listening to all the cr#p they were spouting, and trying to just be quiet and leave before starting anything.

Keep up the good work with your pool--just keep an eye on your filter pressure, because the gray you see is dead algae, which can gunk up a filter in a hurry. Let us know how it goes!!
