I have been playing the pb's game of having techs who don't know anything come out to tell me why my in-floor is not performing properly (getting closer to a resolution with that, I think, finally) and in the meantime I've left a lot more dirt on the floor for a much longer period of time than I would normally so that i could show the pb that the in-floor wasn't working. After a good brushing I found some spots on the floor. Weird that they are more circle spots, (like 4 inch round circles in one area verses feet of staining as the dirt was spread across several feet) (accept one in the corner, which it almost seems dirt could still be stuck in since the brush doesn't seem to fit well in that area (I might buy a rounded brush for the corners). My CC is 0 so it's not algae.
Any info on how to tell if it's a stain and if so, how to get it out... along with tips on fighting with the pool company on this one would be appreciated.
I'm sure someone will want pics and I can get those on here, probably over the weekend. Those things always take me some time. thx!!
