I have a very thin layer of some sort of deposit or scale that is coming through all the return lines in the pool & my spa. This has been going on for about a month now. My PB says "he's heard of that before, but does not know what it is." I haved cleaned my 4 cart filter, shocked, added salt, added acid...blah blah blah & no change! It's consistantly coming out, & not just a little bit. I can hardly keep up with the cleaning...
I really looks just like cracked up egg shells. Ideas?
