Manufacturer Info

Digital Aquatics Aquarium Supplies
Digital Aquatics was founded in 2004 and has quickly become the most recognized name in aquarium automation. Since the company debuted the original ReefKeeper 1 (now known as the RK1) in 2004, they have gone on to create some of the most flexible, innovative and cost effective aquarium controllers on the market. The revolutionary ReefKeeper Elite (RKE) was unveiled in 2008 and the affordable ReefKeeper Lite (RKL) came out shortly thereafter to appeal to more budget-conscience aquarium hobbyists. In 2010, Digital Aquatics released a reptile version, the HerpKeeper, as well as the aptly named PondKeeper. ReefKeeper controllers simplify aquarium keeping duties by monitoring and controlling a variety of water parameters and equipment including but not limited to lighting, water flow, heating, cooling, pH and ORP.

Works Great

unit works great, no need to set up anything to make it work out of the box. it does not come with the 9volt power supply but works fine without it. one benefit of using this hub is that it eliminated having to daisy chain the other modules long distances, which was causing some communication issues and lag. I am using 3 ports, I suppose one may want the added power boost of the 9 volt power supply if you were using all 5 ports.
