Neptune Systems controllers and monitors are some of the most unique and innovative pieces of equipment in the industry. How much would you pay for peace of mind and almost total control over your aquarium from nearly anywhere on earth? With a Neptune unit, you have the ability to monitor and control your aquarium from nearly everywhere. We often wonder at the shop level how many millions of dollars has this company saved the industry because of what their products are able to accomplish. We did carry other monitors and controllers at one point but have since dropped every other brand in favor of Neptune Systems. These units have a wide range of different accessories that can be added to their already extensive list of attributes. Dosers, automatic feeders, pumps, and more only add to the reasons to purchase one of these units for your tank. Another remarkable feature of Apex units is their ability to give every user personal feedback on how their tank is performing in an effort to help every hobbyist maintain their tank at its peak health. If you purchase your Neptune Unit from us we will be here with round the clock support should you have any installation issues.
