  • Neptune Liquid Level Sensor (LLS) 4 Inch. For all Apex aquarium controllers. Apex Fusion display showing Neptune LLS

    Neptune Liquid Level Sensor - 4 Inch

    In Stock

    Neptune Liquid Level Sensor - 4 Inch The Neptune LLS Sensors for your Apex controller allow for the measurement of water depth in inches or centimeters.The Liquid Level Sensor is available in four different sizes- 4", 15" 23" and 35" with each sensor having a special place in helping understand the water level in the sump, aquarium, reservoirs, and other liquid-holding containers.No longer do you need to physically look to see how much water level is above or below a specific point, but now simply open the Apex Fusion App and observe. How the LLS from Neptune works The LLS sensor can connect to any available FMM port in your Apex System. Liquid will enter the plastic envelope around the thin material of the sensor. Once the liquid is in contact with the sensor material the LLS uses a patented resistive sensing technology to accurately and reliably measure the liquid level in a container.Included with each LLS sensor is a clip that allows for the mounting of the sensor to the side of the sump, aquarium or container. You can also mount the LLS sensor to a baffle inside the sump. Once calibrated the LLS is accurate to about two-tenths of an inch. Liquid Level Sensor- 4" Applications The 4" LLS is the smallest of the four sensor offerings. It is the perfect fit for small reservoirs for small sumps, ATO reservoirs and additive containers. The smallest LLS can be a great solution to double check that liquid additions of your additives match your dosing solution over a period of time. For example, if you dosed 250 mL additives over two weeks and you know each inch is 100 mL, then the additive reservoir liquid level would have decreased exactly by 2.5". Application Notes for the LSS The components in the head of the LLS are fully encapsulated in epoxy, but the LLS is not intended to be fully submerged. Care should be taken when selecting the proper length of LLS and installing it to ensure that the water level never exceeds the uppermost graduation mark.

  • Magnetic Optical Sensor (MOS) from Neptune Systems. For the Apex and Apex Junior controllers.

    Neptune Magnetic Optical Sensor

    In Stock

    Magnetic Optical Sensor for Neptune Apex The Neptune Magnetic Optical Sensor replaces the optical sensor with magnet and offers an improved look, feel, and magnetic design that also lends itself to help prevent water incursion into the sensor.The MOS plugs into your FMM and, using reflected infrared light, will signal your Apex when it changes state from being wet to dry or dry to wet. This sensor can be used for constructing your own ATO (auto-top-off), as a high-level warning sensor in your sump, water storage level sensor, and much more. The sensors can be mounted into custom brackets or through a hole in a vessel. Included with the Neptune MOS are a fastening nut and silicone washer.

  • Neptune LD3 Optical Leak detection accessory for all Apex aquarium controllers.

    Neptune Optical Multi-Surface Leak Sensor

    In Stock

    Neptune Apex Optical Multi-Surface Leak Sensor New to the leak detector offerings for your Neptune Apex is the Optical Multi Surface Leak Sensor (LD-3). This is a weighted sensor that is an improved sensor and design over our Solid-Surface Leak Sensor (LD-2). Neptune LD-3 Optical Leak Sensor Improvements An epoxied design that prevents water incursion into the sensor circuitry. This allows the sensor to be utilized over and over despite how often it becomes activated and wet. Utilizing an optical sensor allows the sensor to be placed on any surface including metal and epoxied cement floors without a false activation. This LD-3 Leak Sensor requires an open FMM module port in order to work with your Apex aquarium controller.

  • Red Sea Reef ATO+ Upgrade Kit Red Sea Reef ATO+ Upgrade System overview of set-up system in sump

    Red Sea Reef ATO+ Reefer Upgrade Kit

    In Stock

    Red Sea ReefATO+ Reefer Upgrade Kit Exceptionally reliable and smart ATO, temperature monitor and leak detector The Red SeaReefATO+ is designed to maintain a stable salinity and water volume in a reef aquarium by automatically replenishing the water lost due to evaporation. In addition, the ReefATO+ provides two other critical aquarium health indicators: a fully featured on-line digital temperature monitor and a leak detector. How the ATO Works The EC technology titanium probes detect the water levels that triggers the pump to be switched on and off to maintain a stable water level and salinity. The ATO+ includes the added safety feature of an l-proof (solid-state EC technology) water level sensor with built-in safety shutoff. Automatic shut-down if the sensor is not connected, if the pump runs significantly longer than normal, if the RO reservoir runs out of water or if a leak is detected. Components of the Red Sea 3-in-1 ReefATO+ ATO Sensor - Fail-proof (solid-state EC technology) water level sensor, with built-in back-up pump-OFF probes located 2.5cm / 1" above the normal pump-OFF point. The full array of the Reef-Spec titanium probes gives an indication at all times of the actual water level relative to the sensor, which can be seen on the ReefBeat App at all times. ATO Pump Quiet, variable flow, 12 vdc ATO pump. Cylindrical design with diameter of 4.5cm / 1.8" to fit inside standard jerrycans. Max flow rate 300 lph / 75 gph, Max head 2.5m / 8', power 6-10W. Pump performance monitor in the controller will shut down the pump automatically and let you know through the ReefBeat App if it is not connected, stalls or RO reservoir runs dry. Pump speed is automatically adjusted according to your installation to maintain a flow rate of approximately 72 lph / 18 gph ensuring a splash proof and quiet flow of water into the sump. The noise damping rubber impeller chamber cover and impeller can be removed for pump maintenance. Includes lock-nut on the outlet hose barb for secure connection to the silicon tubing. Leak Detector - The highly sensitive, Reef-Spec leak detector with saltwater resistant titanium probes detects the full range of waters from RODI to seawater. If a leak is detected the ATO Auto-fill is immediately disabled, and after a few seconds to confirm that the leak persists, the controller sounds an optional audible alarm and sends a notification to your mobile device. Connect the Leak Detector to the Emergency Quick-action for the aquarium and ReefBeat eco-system will automatically shut down other ReefBeat devices such as the ReefRun return pumps. Temperature Sensor - The temperature sensor integrated in the ATO+ sensor has been pre-calibrated to give an accuracy of +/-0.1F. The ReefBeat App allows you to set a narrow "desired" temperature range, and a slightly wider "acceptable" range, that will be seen on- line in the ReefBeat App and in the full temperature logs. In the event that the temperature goes outside the acceptable range you will get a notification to your smartphone.The detailed logs will show you the minimum, maximum and average temperatures at 15 minute intervals for the past 28 days. Smart Controller - The micro-processor monitors and reliably controls all of the components and connects them to the ReefBeat eco-system. ReefATO+ Complete Installation Kit 3M / 10' - 1.5mm / 1/16" thick silicone tubing ID 5mm / 0.2" Silent flow - Tube holder, clips on 4 - 12mm / 1/2" glass Siphon breaker Note: If you have a Red Sea Reefer already, save some money and purchase this upgrade kit. It does not include the magnets and bracket needed to holder the sensor that other non Red Sea systems may require.
