Tiny Particles That Look Like Bits Of Plastic Bags

[will_md]

The tub has not been used for a couple of months due to a toasted heater relay/control board which I will order. But we noticed tiny (size of a pencil lead) white particles which I am guessing is calcium. We live in the country with well water, nasty, and run the water through a softener every other time as recommended by our dealer. The spa is six years old, Tiger River Bengal, and we have had no other issues. This is our second Bengal. We use Bromide rather than Chlorine, if I get it right since my wife manages the tub. Someone I know suggested using CLR and I have seen suggestions for a couple of other solutions. Any suggestions?

Thanks,
