I had the pool tested 3 times before and they all said no metals but I can see sparkles floating in the water. Had the water tested again for metals two days ago and still nothing. Also my local pool store called me this morning to see if my water was still green (nice of them) and said they were going to send a tech out here for free just to look at everything (again nice of them). Well the guy showed up around lunch. He noticed all the little crap that's been floating around my pool and decided to but some DE powder in my skimmer (for free) and he was going to leave me 1/4 of a bag (huge bag) but when he did ALL of the powder came shooting out of my jets and my pressure never went up. I had said something to them before about my pressure being low and they said that all pools very so I was no longer concerned about it. Well he advised us to change out the sand, run filter, vacuum on waste again, NOT to add the spring water again, and if I wanted to I could flock (sp?) the pool and then waste the next morning. He also said that my water would remain green till I added the metal stuff BUT to wait until the water reaches 60 degrees??? My stuff is orange!!! :-( Also I tried to rub the tab on steps and it's not doing a great job.. Kinda just grating the tablet... Maybe I need more elbow grease?? :-) Oh.. should I post on Metals part too? Thanks again for all your help Janet!!!
