However, I (the chemist in me) would want to evaluate the possibility that the white powder is a precipitate from a chemical reaction. Something in the fresh water (tap water is treated with lots of chemicals) reacting with something still in the tub. OR, the possibility of some mineral having an extremely high concentration in your water, or something along those lines. Although a mineral would have to be in an extreme quantity to cause the kinds of sediment your talking about.

I'd say it is your baqua spa stuff. That stuff gets in the pipes and sticks to everything. Then when you refill a bunch of the junk comes out and floats around for a while. Try doing a system flush the next time you drain and switch to good old chlorine for the next water change and see if you have the same problem.

I had a problem with white powder in my hot tub, at first I thought that it comes from a pump, due to wear of plastic parts, I took apart the pump outlet pipe, that goes to heater, I realized that pump was clean of contaminant, the pipe all the way to the heater was also clean, but inside of heater was full of white deposit. Then I went to the internet and found this post. I started lookng outside the hot tub system. I have water softening filter, that requires cyclic rinsing. This proces is done automatically, however there is a tank which should be filled up with special salt. I did not fill up the salt tank for a quite some time, and therefore filter rinsing proces was not done correctly. The water contained some mineral, that powderised under heating process, not right away, but after water got warm, and the result was white powder all over the hot tub. After refilling the filter salt tank, and running proper rinsing proces the problem finished.
