I am having a problem with fine white powder coating all of the surfaces in my older above ground blue fiberglass spa, it is nearly perfect in consistancy under 50 power it appears to be crystalin in nature and has clear grains like ground glass and sparkles some in sun light heat tested around 5 grams (alot) only discolors brown under heat on a piece of tin foil on the stove, since it appreared last year and I cleaned out the spa several times this year I have drained and cleaned the spa twice in a month and it is back agian ? there has never been any glass broken that could be subject to the pump impellor milling it down im thinking there may be a problem with the original heater or ozonator, (I use gas now) if they have some sort of glass or quartz like element anyone have any idea what this stuff could be?
