    Can you provide some more details?

    Full set of test results?

    Color of pool before addition of CYA?

    Even discoloration everywhere or spots?

    Copper in water?

    Type of chlorine used?

    How was the cyanuric acid added?

    Equipment details?

    Pictures?

    Good point. It might not have been cyanuric acid. I have never seen CYA cause that type of reaction. The only thing that I can think of would be a reaction with high copper levels, which could cause purple amethyst colored stains.

    Copper can bond with cya to create copper cyanurate, which can cause violet staining. I wonder if that's what's going on.

    Re: Stabilizer turned plaster and tile dark blue??

    The pool was painted light blue..we have a 19 year old kid that services the pool. He told my wife we were losing chlorine so she needed to buy stabilizer. She bought it at Walmart..I added 14lbs through the skimmer basket and had no problems, 3 weeks later pool guy told my wife we needed more..she added 8lbs at the pump..few days later pool started turning dark blue...looks like someone threw in a bunch of those blue cleansers they use in urinals! I'm draining it now..that stuff is really stuck on the tiles..kind of a chalky substance?? I don't know what my levels were as the kid took care of cleaning and chlorinating...think he just added tablets and swept! I have pictures but don't know how to upload.

    No..unfortunately not..but it was stabilizer and conditioner..Walmart brand..TGB or something like that..I did see the bottles after my wife added the stuff..it was the same stuff we used before...the blue is everywhere..not just in spots..looks like someone painted ..some spots on plaster seem to rub off..but tile..nope!!!

    Also...water is NOT blue and skin does not turn blue when it touches water..whatever it was just attached to the pool itself..

    22 lbs is a lot of stabilizer. In 50k gallons, that would raise cya by 53ppm. If he's using pucks, it could've already been high. I'm also curious how she added it at the pump. The blue color just adds to the mystery of the whole situation. A good set of test results would sure help with the big picture.

    She went to the pump, took out the basket, poured in the crystals, put the basket back in (backwards) and turned the pump back on.

    In an inconspicuous area, let a crushed up vitamin c sit on it for a bit and tell us what happen...eg. If it returns to its normal color or not.

    If it does, that means you ay be able to restore your pool with an Ascorbic Acid treatment, but you won't be able to successfully do a treatment without a proper test kit (http://www.tfttestkits.net) and a firm handle on TFP maintenance procedures.

    You do know that your pool can float out of the ground, if you have enough rain/groundwater .....right? Do you have a hydrostatic well?

    Why did you drain it? You need to know that it's much easier to fix most problems with water in the pool? I sure hope it doesn't float out of the ground!!

    You will spend less time and money on your pool of you ditch the pool service companies and the pool store. Then you never have to guess what's going on. Invest im one of the recommended kits and take total control. You won't regret it.

    whoa...you drained a 50,000 gallon pool empty!? are you even allowed to refill it where you are at in California?? really wish you would have waited for some recommendations before you did that, seems like a very drastic course of action. hopefully your water table is deep!
