We're in the process of having a white Leisure bay spa installed in our deck (flush with the deck). We love the look of blue/turquoise swimming pool water and would like to have that in our spa. A dealer mentioned there's a special tint you can add to the water but he didn't carry it. Does anyone know anything about this?

There is a product available:

Party Blue

Party Blue from GLB is a safe water dye that turns your pool or spa water into a sparkling rich caribbean blue. 8oz.

Cost is $9.90 plus shipping. I can do an order for you if you are interested.
