The world of aquariums is evolving, and with it, the technologies for maintaining a perfect marine environment. RED SEA makes your life easier with this Upgrade Kit that allows you to propel your current equipment into the future. It's not just about changing a part, but a complete transformation for your skimmer. Once converted, managing the foam becomes child's play. No more unexpected overflows or the need to constantly monitor the level! The real star is the included foam detector . This little marvel of technology watches over your skimmer while you focus on the beauty of your tank. In case of imminent overflow or malfunction, it sends an alert, guaranteeing the safety of your setup . It's a giant leap towards simplified maintenance and flawless performance, ensuring impeccable water quality for your corals and fish.
This upgrade kit isn't just a set of parts; it's access to the latest innovations from RED SEA . At the heart of this transformation is the integration of a PSK-DC 1200 pump . This DC pump offers variable and adjustable flow , meaning you can precisely adjust foam production to perfectly match your aquarium's specific needs, regardless of the organic load. This flexibility is crucial for achieving maximum skimming efficiency . Of course, to fully utilize these fine adjustments and the renowned foam detector, you'll need the ReefRun Dual Controller (sold separately). This intelligent controller allows you to centralize management and integrate your skimmer into your system's connected ecosystem. The complete package, including the universal power supply and the new REEFER Skimmer 900 cover designed specifically to house the detector, ensures seamless and effortless integration .
