Hello all. I'm new to the forum and some help would be greatly appreciated. When I opened my pool this year I noticed stains everywhere. I tried a couple of products, and Jack's Magic Solution No. 1 supplemented with their "Blue Stuff" worked excellent. I followed the instructions my local pool pro gave me and waited a few days before adding any chlorine. Once I did I noticed the stains came back. This went on for a couple of weeks. Finally I go back to my pool pro and they ran a water test and called jack's magic. Jack's then tells them the Cyanuric Acid is too high (approx. 180 ppm) and the metals couldn't filter out of the water after they lifted off of the liner and steps. They recommended "diluting" the pool by draining and refiling. I've done that once and the cya is down to 135 ppm. My pool pro is now saying I need to drain and refill two more times to get the cya down before I do another Jack's treatment.
I'm trying to see if anyone would recommend another product or another solution that doesn't involve me dumping over 20,000 more gallons of water and going through a couple more hundred dollars in expenses (already spent around $400 on this problem). Any help would be greatly appreciated. Thanks!
