The first question we're typically asked from new Vectra owners, "how should I plumb my Vectra"? Both hard and soft plumbing configurations are available with any model Vectra. It is truly a matter of which is more suitable for your application. If you're unsure which plumbing configuration is best, it would be best to consult your aquarium manufacturer for their recommendation.
The Vectra has built-in Quickcouple connectors that can be glued directly for PVC applications. We also have a barbed adapter and inlet screen available for purchase from our online store here
