If you have not done so already, start by sizing your Vertex system using our sizing calculators, use this one: for a covered spa pool or swim spa or this one: for an uncovered or blanket covered swim spa or small pool. They will tell you if you can get way with using the "Flood Prime" or you need the "Self Prime" system. Listed below is the Self Prime System, if you need to add more panels to this base kit, just use the add-on panel listing. If you get stuck, you can even submit the calculator and we'll get all the details. We're here to help, we love to help - just email us :)
