On my 2003 38 Open I see similar white crystals as you described in the fresh water filter that is between the fresh water tank and the pressure pumps. The filter is located under the cabin floor where the fresh water pumps are...At the end of the season when I winterize the system I remove the screen and clean. I've done this for many years but the amount doesn't seem to affect preformance of the system when running on the pumps... Every once in a while I need to clean the filters at the faucet (galley and/or head).. Haven't seen any problem with shower...
