Hi there - Is there a difference between Stonescapes Touch of Glass and Puerto Rican Blend? The website makes it seem like there is a difference (Puerto Rican blend has maybe smaller glass beads?), but I have a sample that says "Aqua Blue with Touch of Glass, Puerto Rican Blend", which makes it seems like it it combined. The pool supply guy that gave me the sample said Touch of Glass was the new name for Puerto Rican blend, but when I called to clarify, someone said they were two different products. I sure like the look of the sample I have, but am signed up for just mini pebble and am not sure I want to spend extra $$.
