Crushed shells in pebbletec?
We are building a pool in NC and are at the plumbing/electrical stage. We will be having the pebbletec done pretty soon and are contemplating two colors, caribbean and tahoe blue. Tahoe blue would be an upcharge. The pool builder also said that we can (with an additional cost) add crushed shells to the pebbletec to make it "pop". Has anyone done this before and is it worth the additonal cost? Also, does anyone have any pics of their pools with tahoe blue and caribbean blue with or without the shells? Thanks in advance for any help, this is all new and so many decisions to make!
