Digital Aquatics ReefKeeper Systems

With systems starting under $150 ReefKeeper control systems can handle tanks from 10-10000 gallons! Flexibility, expandability, style and function make Digital Aquatics controller a great addition to any tank!

The ReefKeeper Elite is true to its name, standing alone in the industry as the most innovative aquarium controller on the market. With the most intuitive interface and easy use system controls, you`ll find it will simplify all aspects of your aquarium system that it controls. There`s also no need to find a power outlet near the head unit as there`s no power cord needed; power is provided right from the bus. The compact and convenient design, multiple mounting options and great looks makes the ReefKeeper Elite right for almost any installation; and without any unsightly probe wires dangling about, the head unit will add a touch of class to any tank!

The ReefKeeper is the most expandable controller we know of, allowing the control of over 160 outlets. It has the capability of reading more probes and input devices than even the most demanding system will ever need. All this makes the RK Elite suitable for tanks from 1 to 10000 gallons and beyond.

One of the biggest advantages of the RK Elite system is what it comes with! With other controllers you`re left wanting and having to purchase add-ons just to get them to a usable level. The RK Elite system includes two PC4s; that`s 8 outlets to control! You also get an SL1 that will allow you to monitor pH, ORP, temperature and two micro switches. Not to mention a free temperature probe and pH probe. All this for hundreds of dollars less than other controllers that barely give you enough to get started.

System includes:
1 x ReefKeeper Elite Head Unit
1 x RKM-SL1 (pH, ORP, temperature, 2 micro switches)
2 x RKM-PC4 (total of 8 outlets)
1 x Programming Dongle
1 x pH Probe Kit
1 x Temperature Probe

Ethernet Capable
Because the ReefKeeper Elite is a modular system we have the ability to develop new features as time goes on. One feature that we`ve been defining is an Ethernet module that will allow users to take advantage of their home networks and the World Wide Web. Digital Aquatics is dedicated to producing quality products at great prices! This module is still under development and we`re working on every aspect of it to reduce cost to you and NOT compromise safety and functionality. More to come on this optional module.

Wireless Communication
While a USB connection for your ReefKeeper Elite is needed for updates to firmware, nobody wants an unsightly wire running from their ReefKeeper to their PC. This will offer a Zigbee like wireless network experience. While we`re not ready to release all the details, our wireless module will give you freedoms and abilities that other systems just can`t offer. More to come on this optional module.

The RK Elite also has upgradeable firmware so your controller can grow with your system; and firmware updates are always free!

NEW - Advanced 11 button CapSense interface
By expanding from the traditional 3 button interfaces of the past we have given the user a more intuitive interface to navigate with. The RK Elite menu, programming, and viewing systems take full advantage of the new interface providing an all around easier experience.

NEW - 128 x 64 Graphical display (w/RGB backlight and 30 background colors)
The RK Elite utilizes a graphical display that allows us to display status icons, data graphs, and a variety of information in a way that has not been possible before.

NEW - More then 250 Programmable Channels
One of the highlights of the RK Elite system is its ability to control over 250 outlets. While most people will never need that many outlets, some will. Our goal is to be forward thinking and give your new system the freedom to grow.

Multiple Mounting Options
Like the RK1 and RK2 the RK Elite provides for multiple mounting options like flush mount and surface mount. While other controllers are big and awkward to mount needing unstable Velcro or unsightly restraints the RKE will add a touch of class to your system. Let face it, we all work hard to keep our tanks looking good and the RKE will be a great addition!

NEW - Home Screen (w/easy to read icons and data)
The new Home Screen provides you with quick information that is well laid out and easy to read. Icons provide you the current state of your system while you can quickly scroll through all the data for your tank with the touch of a button. Keeping tabs on your tank has never been easier!

Simple menu system for easy configuration
We`ve worked hard to try and make the interface as simple and intuitive as possible for the RK Elite. With the advantage of the new interface we`re able to really produce a one of a kind experience.

Night Mode - Independently Programmable
Our Night Mode feature allows the RK Elite to change depending on the time of day. In Night Mode the RK Elite can activate your Moon Light Controller, dim your display, transitioning your tank into a calm state.

NEW - 64 Alarms
With 64 alarms and an audible and visual alert you`ll know when any of your critical system parameters are out of range.

NEW - Data Logging
The RK Elite has onboard data logging for up to 32 probes/device with over 1000 data points each. NEW - Data Graphing
With our new graphical head unit comes the ability to really display historic data the right way. Our dynamic graphing will help you track the performance of your system over time allowing you to quickly see when and where things are happening.

Metal Halide control with "Sure-On"
Just like the RK1 and RK2 the RK Elite system will make sure your Metal Halide bulbs come back on after a power interruption. Sure-On is a 15 minute delay that gives these expensive and sensitive bulbs time to cool which insures safe, continuing usage over time.

NEW - Light Timer with Weekday/Weekend schedules and safety temp cut off
New to the light timer is the ability to set different lighting modes for weekdays and weekends. This gives you the option of setting a lighting cycle that caters to your viewing schedule as it changes throughout the week. You still have our safety cut off temp that will shut your lights down if your tank gets above some set point.

Moon Light Controller (optional)
With the optional MLC the RK Elite system can simulate a true lunar cycle. Read more on the RKM-MLC in that section.

NEW - Multi-timer function
The multi-timer is all new. You`re now able to stack up to four unique timers to create any on/off cycles you would like. This is great for dosing and other scheduled tasks that don`t happen on a regular interval or for creating your own special cycle based on your needs.

NEW - 64 Dedicated Timers
Ther are 64 advanced timers you can program, and with the Multi-timer you can mix and match them in any fashion you`d like to get even more complexed function.

NEW - 2 Standby/Feed/Service modes
The RK Elite also sports two user settable standby functions. This gives you the flexibility to configure multiple service modes for activities like feeding, water changes, and other maintenance.

Control Functions
The new "Controller" function can take any probe input and act on it with a user settable hysteresis. This includes pH, ORP, temperature and micro switches just for starters. You can also take action based on current draw or load on any PC4 and you`ll be able use any future probes that are added to the system!

Sumps/Skimmers pump control
You can program the sump pump and skimmer pump functions to be off in standby and even have a standby delay just to make sure your system doesn`t overflow or over skim food after a feeding.

Wavemaker A/B and C/D pump control
We`ve expanded our old wavemaker control to include a "D" mode. Now you can set up multiple pairs of power heads to get all the turbulent flow you need!

NEW - Top-off pump control
Use this setting to control a pump based on a micro switch for top-off and many other features.

NEW - Key Lock
Lock out unwanted and accidental usage of your RK Elite. With a simple lock, you can make sure the kids, your friends or anyone else doesn`t mess with your controller.

Battery Backup
The battery in the RK Elite is user serviceable. If it ever goes dead it can be replaced without the need for service.

NEW - Audible Feedback
Also new to the RK Elite is audible feedback. You can turn this feature on or off depending on your preference.

Splash-proof Faceplate
Wet fingers aren`t a problem with our full covering face plate.

Upgradeable Firmware
Like the RK2 before it the RK Elite has upgradeable firmware. This will help you maintain your investment over time and allow you it grow as we release more and more expandability!

Good at first, Crap over time

I bought the light then the elite and I can tell you that it starts out fine and turns into garbage over time. First it was the net module being slow and unresponsive. Sent it to DA who did tests on it and after 6 weeks they sent me a new one. Then it turned into modules failing and having to be replaced. Then parts or the whole system will just crash. SLX will just stop working. It will show error for anything the module does. So my heater and ATO will no longer be working. I will come home to a take with raised salinity, missing half a gallon of water. My temp will drop down to room temperature. I lost about 2k worth of corals and fish because i went on Christmas vacation and my tank dropped down to about 65 killing everything. Now the whole system just randomly reboots. Came home and my lights would flash every few minutes and my pumps would shut off. I no longer trust the system. My pumps and heater are plugged into a power strip and I add water manually. I monitor temperature with thermometers. The only thing it does now is control the lights. Stay away from DA if you value your animals.

Needs better support

I have used both models of the ReefKeeper and even though it works for basic uses the software is rarely updated even when a glitch is found. I had problems with the heater control, devices not turning off, failed outlets. Their NET unit is only good for programming without using a cable or turning things on and off. They do not even have an official DA app on iOS or Android. I just hooked up an Apex and it is leaps and bounds better on the hardware and software side. Some of the extra add ons for the ReefKeeper are standard on the Apex.

Faulty product / no service

Ordered over $1,200 worth of the system. Attempted to set it up piece by piece. Worked ok until adding the third module then constantly started loosing time. Sent in head unit for replacement. Received replacement, system constantly rebooted itself. Attempted to contact customer service, their response will always be disconnect EVERY module then start adding them back one at a time until the reboot happens. Good idea unless you have 12 modules and the reboot is only happening intermittently. System now reboots constantly and DA refuses to replace it. Piece of junk, not worth the time. Highly suggest you don't purchase.

Good customer service

When I opened the box I was missing the bus cables to link the system together, there's no instructions to set it up you have to go to there website to figure it out. There customer service is excellent they sent out the cables right away. Now I got it hooked up and running but my head unit has a bad connection, if I bump the cable it resets the head unit. They sent a new one and I am waiting on that. I give there customer support 5 stars, the system operations 5 stars, the the lack of instructions and cables is why I gave it 3 stars.

Barely Operational

I will list the problems: Does not save data unless PC is connected full time (logging function removed in firmware update). Will not stay connected to PC if you turn on/off. 'Low power device' DA support suggests adding a surge suppressor to each outlet to mask this problem. USB ground loop causes inconsistent pH readings, must use PC with no grounding. Graphing is buggy, the data scrolls off the right side of the chart. For the price there are much better options.

DA ReefKeeper Elite

I've had mine running for about six months now with little problems. If you are looking for a controller it is hard to go wrong with this one. If you have a planted tank the lite model is great for CO2 control plus it will take care of temp and lights. It allows for more advanced setup than timers and CO2 controllers do. HELPFUL HINT When you install the controller put some tape over any unused buses and switch or probe jacks.

Lots of BUGS

I have been running this system for 8 months. It is good at shutting lights and pumps off and on... BUT my pH probe will not stay calibrate. Now my Temp probe. My heater cooked a tank to 111 F because the probe was reading -17.3.
