New plan for fountain display!

So, my nozzle, acrylic rod, and more pumps come in tomorrow. I decided I want to make a musical fountain display that I could manually operate or have it run by program. Hopefully, this will allow for more creativity and various display options. I bought an Elation T20 to control the in-water jets, a Chavuet LED 36 can light, and an American DJ RGB controller. I still need to figure out where to buy cheap fiber optic wires or an alternative. Any ideas? I'd prefer to buy something in-store or make it so I could work with it right away.
