Aquarium Supply Info


Aquarium controllers offer an easy and convenient way to maintain almost every aspect of your aquarium. Hobbyists can now simulate sunrise and sunset, lunar cycles, create custom feed modes, control any and every component in their system (protein skimmer, return pump, powerheads, etc), automatically top off, as well as obtain continuous readings of their aquarium’s pH, ORP, salinity or temperature. Newer aquarium controllers now offer the ability for remote control either through a web site or even an iPhone app. Most new web modules allow the hobbyist to display their current water parameters, as well as other information, on any web site.

Aquarium controllers can provide a peace of mind as they not only monitor current conditions, but can respond in real-time to the ever changing parameters in our aquarium systems. The hobbyists can instruct the aquarium controller to maintain a desired water temperature, automatically turning heaters, fans, and chillers on and off. Rules can also be set to protect the aquarium from disaster. For example, if a system overheats, the aquarium controller can be set to turn off any lighting that may be on, even if this conflicts with the set lighting schedule.

Many hobbyists use their aquarium controllers to monitor their calcium reactors. The aquarium controller is able to toggle the solenoid on CO2 regulators (for pH control inside the reactor). This replaces the need for a standalone monitor commonly used for this purpose.

New technologies are only going to make aquarium controllers better and easier to use. There are many excellent choices out there for today’s hobbyists.

Wave Surfer Electronic Controller by Sicce

Posted on Thursday, March 10th, 2011 at 12:17 pm

The all new Wave Surfer Electronic Controller by Sicce simulates the type of flow found in nature. Designs to deliver trouble-free performance and coupled with ease of use, the Wave Surfer Electronic Controller allows for multiple currents from various directions inside your tank. Setting and modifying powerhead timing is simple, and you’re able to set both Feeding Mode, and Night Mode. Sicce recommends using the Wave Surfer with a Sicce Voyager and Syncra pumps, but in truth it can be used with any controllable stream pump, as long as a limit of 100 watts total for each of the two outlets is not exceeded.

ReefKeeper Lite – Digital Aquatics

Posted on Friday, June 5th, 2009 at 4:48 am

The new ReefKeeper Lite is a big change to business as usual! It’s small, expandable and perfect for nano tanks, beginners, and people looking for a mid level controller!

The ReefKeeper Lite or RKL as it’s known here, has a 5 (mechanical) button interface and a larger 16 x 2 LCD display for easy readability. While some of the advanced modules and features of the RKE are not available for the RKL, it will have more than enough power to monitor and control single tank systems, as well as small to mid sized tanks alike!

The RKL is the only controller under $150 that offers four outlets and temperature control while still providing the customer an upgrade path as their system or needs grow!

With up to four modules, this new controller is perfect for streamlining your tank without breaking the bank!
Three levels to pick from:
Level 1: ($99.99)
1 x Head unit
1 x PC4 (4 outlets)
1 x temperature probe

Level 2: ($209)
1 x Head unit
1 x PC4 (4 outlets)
1 x SL1 (Inputs: pH, ORP, Temperature, 2 x Switch Ports)
1 x Temperature probe

Level 3: ($279)
1 x Head unit
2 x PC4 (total of 8 outlets)
1 x SL1 (Inputs: pH, ORP, Temperature, 2 x Switch Ports)
1 x Temperature probe
1 x FREE Digital Aquatics pH probe
Any level you purchase can be added to, up to the four module limit. The RKL can interface with PC4s, SL1s, and the MLC. It can NOT interface with the SL2, NET and other modules yet to be released. Those modules require the RKE system with more advanced features and abilities.

ReefKeeper Elite by Digital Aquatics

Posted on Thursday, May 28th, 2009 at 4:20 pm


Product Description
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 to 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 250 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 RKE suitable for tanks from 1 to 10,000 gallons and beyond.

One of the biggest advantages of the RKE system is what it comes with! Other controllers leave you wanting and having to purchase add-ons just to get them to a usable level. The RKE 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 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.
Three Packages to choose from:
RKE Basic: ($299)
1 x ReefKeeper Elite Head Unit (GC1)
1 x RKM-PC4 (total of 4 outlets)

RKE Standard: ($490)
1 x ReefKeeper Elite Head Unit (GC1)
2 x RKM-PC4 (total of 8 outlets)
1 x RKM-SL1 (Inputs: pH, ORP, Temperature, 2 x Switch Ports)
1 x Temperature probe
1 x Digital Aquatics pH probe

RKE w/NET: ($590)
1 x ReefKeeper Elite Head Unit (GC1)
2 x RKM-PC4 (total of 8 outlets)
1 x RKM-SL1 (Inputs: pH, ORP, Temperature, 2 x Switch Ports)
1 x Temperature probe
1 x Digital Aquatics pH 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
A USB connection for your ReefKeeper Elite is needed for updates to firmware. However with additional hardware you can monitor your RKE with over 802.11, either within your home network or over the internet.

The RKE 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 than 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 – 63 Alarms
With 63 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 – 63 Dedicated Timers
There are 63 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 complex functions.
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!

    The Apex has a special control function which can be used to simulate the varying lengths of days throughout the year. This feature is used to make the length of daylight hours longer in the summer than in the winter. This results in a more realistic simulation of natural lighting variations.

    Moon Cycle Simulation

    The Apex has another special control function which can be used to simulate the moon cycle in your tank. The lunar simulator is used for this feature and is capable of varying the intensity of light emitted from its LEDs. The intensity variations are controlled by the Apex which is preprogrammed with correct intensity values for each day of the moon cycle. The Apex automatically updates the intensity value depending upon the current setting of the Apex’s clock. With this artificial moon cycle, it is possible to induce corals and fish to spawn.


    Each pump to be controlled can either have a random or fixed time period. Both the on and off times are fully programmable and can range from 1 minute to 4 hours in 1 minute increments. Up to 20 pumps can be controlled by one base unit. A variable length feed timer cycle can be initiated with the press of a button and will disable some or all of the pumps in the system (programmed by the user).

    6 Digital Inputs

    The Apex comes equipped with 6TTL level external inputs which can be used to activate/deactivate equipment in response to an external stimulus. Applications for these inputs include connection to water level float switches, water pressure and flow sensors, and water on the floor sensors. The Apex can be configured to signal alarms or turn on/off appliances in the event of external switch open or closure.
