Just bought a Neptune Controller? Check out all of the top Apex Ready reef gear that we carry. Need a pump, check out Reef Octopus Varios Pumps or if your budget allows, nothing can beat the performance of Abyzz pumps. In the market for a new skimmer or calcium reactor? All Varios powered skimmers and calcium reactors are fully compatible with Apex Controllers. Ecotech Marine's Vortech powerheads can wirelessly communicate with the Neptune WXM module along with the Radion Lights, giving you one source of software for your whole aquarium. Apex controller add-on items are almost endless, and in most cases require some type of auxiliary module or connection cable. If you are not sure what you need, give us a call or email and we would love to help you set up your dream aquarium controller!
