    Hydros Rope Leak Sensor Kit

    In Stock

    The HYDROS Leak Detection Rope Sensor is the first of its kind in the aquarium industry. The moment water comes into contact with it, that information can be used to alert you on your smartphone, sound an alarm, turn pumps off, and other actions that can protect your aquarium, home, or office from a total disaster.A problem with traditional solid surface leak sensors is that you have to buy several to really feel a sense of security. What are the odds water will pool in the exact spot where a single sensor sits?Another solution we've come up with is a rope-style water sensor. You can wrap it around your aquarium, sump, stand, or wherever else you like. This type of sensor makes a lot more sense when you want leak detection security in a wider area. You can configure the HYDROS app to perform whatever action(s) you want to happen when a leak is detected: flash a specific light color on your HYDROS controller, turn off a pump, shut down your protein skimmer, send you a mobile alert so you can come home (or ask a friend to check on the tank). It's easy to do and you're in control.Just plug the rope sensor into a Sense Port on your HYDROS device. Next, place the rope flat on the surface where liquid detection is desired. If tape is required to hold the rope in place, be sure to only apply it on the ends. You want to expose as much of the sensor as possible for maximum protection. Once the rope sensor is in place, it is very important to test it to ensure it's working properly. To perform a test, open the HYDROS app on your mobile device and configure the Sense port so the rope sensor is on. Drip a bit of tap water across the rope sensor so the black and white sensing cables come into contact with the liquid. Monitor the sensor's status in the HYDROS app to see check if it's reading is dry or wet. If everything looks good, you're done! Dry the cable and you're ready to configure alerts and equipment to take action if a leak occurs.You don't have to occupy another Sense port to secure a larger area. HYDROS Leak Detection Rope Sensors can be daisy-chained together to form a larger perimeter for protection. Got a big tank? You can lengthen the line of defense to lasso around your large aquarium by simply connecting multiple rope sensors together. Leak detector ropes do not need an additional power source, even if you connect them together. Rope leak detectors do not occupy outlets on power strips or require a HYDROS Drive port connection to operate.HYDROS Leak Detection Rope Sensors offer users 24/7 remote monitoring. Be instantly notified at the first sign of a leak so you can prevent a flood. Tap into the HYDROS app to immediately check the status of water parameters, equipment, power strips, and smart plugs. Make decisions based on real-time data to take appropriate corrective actions from anywhere and at any time.10 ways you can use the HYDROS Leak Detector Rope Place it alongside your aquarium Line it outside of your sum Wrap it around a reactor Lay it on the floor in an open area Fit it into a hard-to-read corner Wrap around plumbing pipes Mount it to a controller board Use it in your mixing station Affix it to water supply and return lines Remotely in your garage, bathroom, basement, laundry room, kitchen, or wherever you make or use water.

    Neptune Apex A3 Aquarium Controller

    In Stock

    Neptune Apex A3 Aquarium Controller Core control and everyday monitoring your aquarium. Overview The Apex System offers the control but with scaled back monitoring when compared to the Apex Pro. The Apex come with room to grow should you wish more features down the road. Prevents catastrophes by monitoring key parameters in your aquarium, takes corrective actions for you, and alerts you via your smart phone when things go off track. Monitors your equipment - ensuring it is operating correctly at all times - and lets you know when it's not. Tracks your manual test results, maintenance, livestock purchases, and tank observations and helps you can correlate issues in your aquarium to the things that are happening inside. Manages the full operation of equipment (lights, pumps, filters, ATO, etc.) on your tank with simple setup wizards and an easy to use app. Takes the place of many costly and cumbersome discrete components such as light timers, heater controllers, pump controllers, etc. Gives you the peace of mind to know how your aquarium is doing, instantly, from anywhere in the world. Features Onboard FMM accessory ports. The Apex Pro has a total of 3 Includes the new and improved Magnetic Optical Sensor Includes the Sold Surface Leak Sensor (LD-2) Includes the new and improved Temperature Probe Neptune Apex is Wireless Internet Ready! For years we have advocated a wired network connection for your Apex due to its superior reliability - and we still do. However, for many people a wired connection is just not possible. So, for this Apex we spent countless man-hours developing an incredible 802.11g/n Wi-Fi connection with reliability that rivals a wired connection. And, the connection process to your home network is amazingly simple - getting you set up and on the Apex Fusion cloud service in just a couple of minutes! Apex Energy Bar 832 Ultimate Power Control Hub This Energy Bar 832 was redesigned from the ground up. Not only does it have eight 120V AC outlets, but it includes an internal 100W 24VDC power supply as well. That power supply feeds three built-in 1LINK ports as well as two 24VDC accessory ports. Each individual outlet has power monitoring and there are individual LED indicators for each outlet. Read on and watch the videos for more info.Apex Power Monitoring: For years we have been asked to do the power monitoring of the individual devices connected to each outlet - but it just wasn't possible without breaking your bank. Now it's here and with comes tons of benefits. For many the cost of the electricity to run a successful aquarium is a major concern in their household. Even for those where electricity is cheap, we believe most aquarists care a great deal about their energy consumption and its effect on the environment. Ironically, our energy usage could be directly connected to excess greenhouse gasses, the warming of the oceans, and the bleaching of the corals! However, armed with the right information we believe aquarists will not only be able to make operating and purchase decisions that will save them hundreds of dollars a year, but they will also be able to reduce their carbon footprint.Built-In 1Link and 24VDC Ports on the Neptune Apex: This Energy Bar has a built-in 100W, 24VDC power supply that can control up to three Neptune Systems 1LINK products like the WAV and DOS. It also includes two switchable 24V DC on/off outlets that are compatible with any 24V device under 30W and Neptune Systems 24V accessories like our Practical Multi-purpose Utility Pump (PMUP).Individual Outlet Indicator LED: Each Energy Bar AC outlet as well as the two 24VDC accessory ports have their own status LED. This LED tells you when that outlet is energized. The LED will also blink rapidly if a device is plugged in that exceeds the current capability for that outlet.The Neptune Apex offers Alarms and Decisions based on Power: Since the Apex is receiving continual power usage data from the Energy Bar 832, it can be configured to send you notifications when a device is not using power as it should be. An example would be a return pump showing no power consumption when the outlet is on or a skimmer whose power consumption will show differently when its airline is clogged when compared to normal operation. These high and low limits are completed customizable by individual outlet. You can even use this power data to control other devices.All Outlets Relay Switched on the Apex EB832: Times have changed and it is fairly uncommon now for aquariums to have AC devices that must be cycled on and off continuously. This means that we could now switch all AC outlets to relay switching since there is no need to have soft start and there is no concern for the noise of the relay. 11 Total Connections Available on your Neptune Apex! 8 - 120V AC Outlets all switched with relays rated for millions of cycles3 - 1LINK 24VDC Smart outlets for devices such as WAV, DOS, etc. What is included in your Neptune Apex Box 1 - Neptune Apex Base System 1 - Energy Bar 832 1 - Temperature Probe - new design 1 - Double Junction pH Probe 3 - Built in FMM ports 1 - Optical Magnetic Sensor 1 - Solid Surface Leak Sensor (LD-2) See images for product comparisons and what is included with the different models.

  • Neptune ORP Probe Neptune ORP Probe close-up view of orp probe tip

    Neptune ORP Probe

    Neptune ORP Probe Overview Neptune now offers both the ORP and pH probes in a double-junction construction for the Apex controller - these probes are built so they hold calibration longer and have a longer lifespan than single-junction probes. Single junction probes put the reference electrode in direct contact with aquarium water. Over time, the junction will slowly leak aquarium water into the electrolyte which changes the accuracy of the probe and requires more frequent calibrations. Double junction probes place a second vessel inside the main electrolyte with a second internal junction. The means that even when the aquarium water eventually begins to make its way in the first compartment, it still has to go through the second junction to contaminate the electrolyte surrounding the reference electrode. These probes will not only work with your Neptune Apex but virtually any other controller or monitor that uses BNC connections.

    The HYDROS Skimmer Sensor serves a very specific and important role: it prevents your protein skimmer from overflowing onto the floor or back into your sump.The way it works is easy: just place the sensor inside any protein skimmer collection cup up to 1/4" thick. There is a magnetic coupling that will sit on the outside of the skimmer cup to keep the sensor securely in place. Once the waste level in the collection cup rises to the point it makes contact with the sensor, it will tell HYDROS to turn the protein skimmer off to prevent overflowing. Your protein skimmer must be plugged into a HYDROS power source, like the Power 4 power strip or Smart Plug, for this sort of skimmer security to operate.The HYDROS Skimmer Sensor plugs into any HYDROS Sense Port and does not require any additional power supply. The optical eye on this sensor is designed to be used inside the collection cup of a protein skimmer, so it's a little different than a standard water level sensor - but purpose-built for this specific and important application. The sensor contains no moving parts that can fail. It's extremely tiny: it's a little over a half-inch thick with a circumference the size of a US penny. The optical eye is magnetically coupled with the magnet side measuring only 1/4" thick. The cord is on the magnet side so installation is easy. You don't need to purchase a new lid for your skimmer or modify the collection cup in any way.The HYDROS Skimmer Sensor is an Official HYDROS Accessory manufactured by AutoAqua in Taiwan. Creators of the Smart ATO Micro, AutoAqua is one of the most well-known and trusted makers of aquarium automation systems in the hobby today. CoralVue has thoroughly tested the Skimmer Sensor to ensure seamless compatibility with the HYDROS platform. The product development team at CoralVue engineered the sensor so it connects with any HYDROS Sense Port using its aviation-style plug for safe operation.

You can connect the solenoid to your reverse osmosis filter and use it to top-off your tank if you don't have the room available for a separate ATO reservoir.The HYDROS DC Solenoid Valve works in conjunction with a HYDROS aquarium controller and an optical or mechanical water level sensor. When the sensor detects the water level is low, it opens the valve to allow fresh RO or RO/DI water to flow through and top-off your tank or sump. When the sensor senses that the water level is replenished, it will tell the Control 2 or Control 4 to shut off power to the solenoid. This closes the valve to stop the flow of reverse osmosis water. The HYDROS DC Solenoid Valve should be connected to the product line coming off your reverse osmosis system. It has 1/4" push-connect fittings to insert standard RO tubing quickly and easily.Instead of using the HYDROS DC Micro Pump as your ATO pump, you can use the HYDROS DC Solenoid Valve instead. Just plug it into a Drive Port on the Control 2 or Control 4 for power and control and configure in the HYDROS app. It is recommended to install an auto-shutoff valve and check valve on your reverse osmosis system to prevent it from producing wastewater when the solenoid is closed.The HYDROS DC Solenoid Valve is an Official HYDROS Accessory manufactured by AutoAqua in Taiwan. Creators of the Smart ATO Micro, AutoAqua is one of the most well-known and trusted makers of ATO systems in the aquarium hobby today. CoralVue has thoroughly tested the DC Solenoid Valve to ensure seamless compatibility with the HYDROS platform. The product development team at CoralVue engineered the solenoid so it connects with a Drive Port on the controller using an aviation-style plug for safer operation. No additional power source is needed to run the solenoid.HYDROS DC Solenoid Valve Specs Max Pressure: 120 PSI The HYDROS DC Solenoid Valve uses a GX12 aviation-style connector so the Control 2 and Control 4 maintain their IP65-rating (dust-tight and protected from water spray at any angle). Powered and controlled by plugging into a Drive Port on the HYDROS Control 2 or Control 4. No additional power cord is required. Manufactured by AutoAqua, an official HYDROS Technology Partner.
