It is not shells...it is what happens when uric acid mixes with salt water. The standard preventative treatment is to flush vinegar slowly through the system once a month...over a couple of hours.
Once you HAVE the problem...the solution is to flush muriatic acid through the system. Do a search here on muriatic for a complete procedure. Problem solved.
