IMPORTANT NOTE FOR INTERNATIONAL CUSTOMERS: The EnergyBar 832 is for use in North America (USA, Canada, and parts of Mexico) and other locales where the electrical service grid provides 120VAC 60Hz power.  For sale in international regions which use 230VAC 50Hz power, Apex systems are bundled with an EnergyBar 6 equipped with 6 outlets specific to that region (UK, EU, AU, or Schuko). EnergyBar 6 models do not include the EB832’s per-outlet power monitoring, 1LINK or DC24 ports, or per-outlet indicator LEDs.

THE APEX ECOSPHERE-- LESS HASSLE, MORE SUCCESS

Neptune Systems Apex Energy Bar 632 UK

When they decided to create an Energy Bar for this new Apex, it was designed from scratch. The Energy Bar 632 not only has six 240V AC outputs, but also includes an internal 100W 24VDC power supply. That power supply powers three built-in 1LINK ports and two 24VDC accessory ports. Each individual outlet has independent power monitoring and there are individual LED indicators for each outlet. This LED indicates when the outlet is powered. The LED flashes when there is an overload.

The safety of our customers is important. That’s why we design every product according to established safety standards. In the case of the Energy Bar 632, we have gone a step further and the Energy Bar 632 now also meets the CE safety standards.

Feedback from our customers has led to our Energy Bar undergoing significant developments. For years it has been requested to provide a power supply for all individual devices, but it was not possible without pricing the product out of the market. Now it’s here and comes with tons of benefits.

With this new Energy Bar 632 you now know when the pump, skimmer, UV device or other device is not operating properly and an alert message can be sent. This enables you to catch problems as they arise and prevent them from getting worse.

Since the Apex receives continuous power consumption data from the Energy Bar 632, it can be set up to notify you when a device is not using power. An example would be a return pump that shows no power consumption. Or when a skimmer has a clogged airline because the power consumption is different than normal. These high and low limits can be customized for each individual outlet.

With all the functionalities of the Energy Bar 632, it is almost indispensable. For an excellent result and good health of your fish and coral you have a bigger chance of successfully maintaining your aquarium. The Energy Bar 632 is compatible with the ApexEL Entry Level Kit and the Apex Lab Grade Kit

11 Total power connections for your aquarium devices
6x 240V AC Outlets all switched with relays rated for millions of cycles
3x 1Link 24VDC Smart outlets for devices such as WAV, DOS, etc.
2x Switchable 24VDC outlets for accessories such as small pumps, solenoids, fans etc.
Built-in 1—W 24V DC Power Supply
Individual outlet current monitoring with specialized software to help optimize control and use less power.

*NEW* LLS Liquid Level Sensor

The Neptune LLS is a first of its kind industry exclusive! While most liquid level sensors simply measure the presence or absence of liquid at a predetermined  sensor height, the LLS is one continuous vertical sensor that can identify the exact depth of a liquid in both inches and centimeters at any given time. This increased sensitivity in measurement can help you identify and be alerted of changes in evaporation, consumption, and dosing levels within sumps, ATO reservoirs, AIO tanks, dosing containers, mixing stations, and more. The Apex can then be set to send alerts or to take action whenever the liquid level changes by a specified amount. All measurements are shown in both digital and animated visual readouts in the app, allowing you to track your liquid level over time. The opportunities and potential uses for this new sensor technology are endless for automating and optimizing your aquarium system.

*NEW* LD-3 Optical Multi-Surface Leak Sensor

Neptune's LD-3 Multi-Surface Optical Leak Sensor marks a significant improvement over its analog counterpart, the LD-2 Solid Surface Leak Detection Probe. While the LD-2 utilizes conductive strips to detect fluid leaks on surfaces around your aquarium, the LD-3 takes advantage of optical sensor technology instead. This shift in sensor technology gives the LD-3 two distinct advantages over the LD-2:

Reusable and resistant to corrosion. The LD-3 sensor can be reused after contact with water. Unlike the conductive strips of the LD-2 which are prone to corrosion from contact with saltwater, the LD-3's epoxy-coated optical sensors can continue to provide long-lasting leak detection after repeated contact with saltwater & with no risk of corrosion!
Multi-surface applications with no false alarms. The conductive strips used on the LD-2 can sometimes give a false alarm when placed on metallic surfaces. With its optical sensor, the LD-3 can effectively be used on any surface material type, including metal and epoxied cement, without the risk of triggering false alarms.

Lab Grade, Double Junction Probes 

The Apex Pro system includes high-quality probes for monitoring your tank's temperature, pH, and ORP. Calibration is a quick and simple process via the app dashboard, which will automatically recognize when your readings have stabilized and letting you know when to move to the next step-- no more guesswork and reading RAW data. In addition, the double junction pH and ORP probes will allow your readings to stay more stable without the need to calibrate as often.

Backwards Compatible

If you have any old modules, head units, energy bars, or other Apex accessories they will work flawlessly with the new Apex Controller.

Awesome robo-vac/mop with rotating mop head/no pads.
Size: E25 Black
I owned a Narwal Freo for 1 year and it died right after the warranty period was up. Tried replacing the battery but that did not fix the issue so I had to purchase another one. I noticed this eufy had high reviews and the 1 star reviews seemed to be just isolated issues so I purchased this one. Right away I noticed that the instructions/setup was much more simple. Second this one has a big wide mop roller on the front and after mopping I didn't see the mop streaks in circular patterns on the floor like I did with the Narwal as it had two rotating mop heads on the front so the single mop roller seems to be a better solution. Setup consisted of removing protective wrappers off of the tanks and base station, filling up the clean water tank, installing the detergent bottle and plugging it in. Next I downloaded the app and connecting the vac/mop to my network. This was SIMPLE to say the least. From there I could have just clicked clean on the app and it would clean the entire house. However, mapping gives you more flexibility when planning your cleaning ritual. You can define no go zones and clean rooms in any order you choose. I have a shedding dog so I have a separate robovac to clean up the dog hair prior to vac/mopping. This is a MUST with any robovac/mop combo as the dog hair on the floor will mix with the water and detergent and eventually prevent the mop from doing a good job. It will make a mess in the bottom tray of the base station too. I learned this through experience and reading all the one star reviews from customers. Robovac only cleaners last a LONG time. I had one that is still working great for over 3 years. All I had to do was replace the battery so it doesn't have to pause the job to recharge. So the mapping only took 4 minutes and it was pretty accurate. After the mapping I defined the room boundaries and renamed the rooms. Next I sent it off to clean and it did a FABULOUS JOB! No streaks and the floors are clean. The noise level is really low and more quiet than the Narwal. The other thing I noticed is it didn't use up much water to rinse the mop while cleaning. The Narwal used a lot of water and I was always dumping dirty water and adding fresh. I will always have a robomop and robovac as they save me so much time by not having to do this job twice a week. Connectivity to my network is excellent as it's in a location far from the router. This vac/mop is a good value for the money if IT LASTS BEYOND 1 YEAR. I will update this review as necessary and if it fails right after the warranty period I will report and downgrade this review to 1 star. These companies need to learn the importance of reliability and correct these issues. When I first reviewed the NARWAL it had almost a perfect 5 star review from all customers. After the year was up and it failed that star rating went down to 3+ stars. Most reviews reported their robovac/mop just died like mine did after the warranty period. I downgraded my review and reported the issue. I'm hoping this one will last because at the moment I am VERY satisfied with it like most customers. This model has been on the market much longer at the time of purchase so I would suspect if there were any reliability flaws they would have been addressed and corrected by now. We shall see. At this time I highly recommend!!

Excellent Robot Vacuum, Especially for the Price
Size: 11S, Size: 11S
I have been an iRobot Roomba buyer since 2007. My last Roomba bit the dust this month, and I did a ton of research before buying a replacement. I went with the Eufy for a few reasons: price point, cleaning power, quietness, and sleek design. Price: Very reasonable. Almost reasonable enough that I'd consider getting another one for my second floor. For now I'll just carry it upstairs. Cleaning power: This thing sucks... It's suction is much stronger than my Roombas have had. It picks up so much dust and pet hair. We do a full vacuum every other week with my Dyson, so I think of the robot vacuum as a supplemental vacuum. I was shocked at how much was in the dustbin after it's inaugural cleaning! The picture attached to this is from that cleaning. It also gets a ton of dust in the little dust filter. In one of the video reviews I watched, the reviewer said it didn't pick up anything in that dust filter... So maybe my carpet is particularly dusty, because it has a thick layer after each cleaning. Quietness: I work from my home office, and this thing is quiet enough that I don't even turn it off during conference calls. This might be the thing I am most impressed with. My last Roomba was LOUD-- you couldn't even have a conversation with someone in the same room, let alone someone on speakerphone. Sleek design: I love/hate this. It definitely looks modern and cool, and more like an art piece than an appliance, but it shows all my finger prints, and now I keep a glasses cleaning cloth nearby so I can rub it down. I suppose if I only use the remote and never pick it up, this won't be an issue. A few considerations: I was hoping to find a robot vacuum that wouldn't eat my carpets' tassels, but I don't think that vacuum exists. I have only used the Eufy 4 times so far, and it doesn't always get its brushes wrapped around the long tassels, but it does sometimes. It seems to realize it sooner than my Roomba did at least. The Roomba would sometimes rip gobs of them off in a single cleaning. I try to tuck them under the edge of the rug and that doesn't seem to bother Eufy. It has pulled off probably 2 tassels so far. The cleaning pattern seems pretty random. I saw some other vacuums that chart out complex maps of your home, and Eufy doesn't seem to do that. But, it doesn't seem to matter, because it still hits every spot in the rooms. I'm a little concerned about durability. My Roombas ran for many, many years with easily replaceable parts. We'll have to see if Eufy has the same longevity. All in all- I'm very happy with my purchase and definitely recommend it!

Robot Vacuum With Decent Cleaning but Too Much Maintenance
Size: E28
This robot vacuum was fairly simple to set up, and the battery life is actually pretty good. When it comes to cleaning, it does a solid job picking up dirt and debris, and overall the suction works well for everyday vacuuming. However, the navigation and sensors really missed the mark for me. It struggled to recognize certain items around my house. For example, the mat under my cat’s food bowl kept getting caught because the vacuum didn’t detect it properly. It also had trouble recognizing furniture like my ottomans and would repeatedly run into them. Another issue was how it handled different floor types. It’s supposed to be able to recognize surfaces like carpet versus hard flooring, but that didn’t always work correctly. At one point it even tried cleaning my carpet when it shouldn’t have. It also struggled with room detection and didn’t consistently recognize different areas of my home, even when placed directly in them. I bought this hoping for more of a “set it and forget it” type of appliance since I work a lot and wanted something that would keep my floors clean without much attention. Unfortunately, that wasn’t my experience. I often had to redo the mapping or move the vacuum around so it could recognize spaces and objects properly. There were a few positives though. The app is very helpful and easy to use, and the vacuum communicates clearly through notifications. It lets you know when things like the water level or cleaning bin need attention, which I appreciated. Maintenance like emptying it isn’t required very often either. It’s also a little noisy. Not extremely loud, but it talks frequently and you definitely know when it’s running. Since I work third shift and sleep during the day, that was a bit frustrating. Another issue was that it struggled to cross small entry thresholds between rooms. Even a small lip between rooms would sometimes stop it from moving into another space. In the end, I decided to return it. While it does vacuum fairly well, the navigation issues and constant adjustments made it more of a hassle than a convenience. For the price, I expected something more hands-off, and unfortunately it required more attention than it was worth for me.
