Affordable Flexability
The ReefKeeper Lite is a powerful and cost effective aquarium control system. It’s completely flexible and allows you the ability to create a control system that’s as unique as your tank. Whether you’re looking for a variety of programmable outlets or need to monitor multiple parameters, the ReefKeeper Lite can be configured to your specifications.

Our easiest programming yet...
The ReefKeeper Lite uses our new “EasyFlow” menu structure which makes for quick setup of the entire system. There’s no complicated or frustrating computer language to learn with the ReefKeeper. We walk you through the setup step by step making sure you don’t forget a critical setting. This helps ensure that the system operates as you expect it to. We’ve also added the new “ReadyFit” functions for programming channels. These functions are preconfigured with some of the more common settings and require little or no input from the user to function.

pH Control
With the ability to monitor multiple pH probes you can run a reactor as well as monitor the pH of your main system.

Temperature Control
Control dual stage heating and cooling with heaters, chillers and fans with different set points. Everything you need to hold your temperature rock solid.

ORP Control
Whether you’re dosing ozone or just want to keep an eye on ORP the ReefKeeper has you covered.

Salinity Control
Use this probe to make sure your water changes are spot on. Consistent salt levels between mix water and system water is critical to the heath of your system.

Auto Top-off
When paired with one or more float switches you can set the system up to add RO water in as small or big amounts as needed. This level of control helps reduce fluctuations in salt levels as well as temperature and other important parameters.

With four unique programmable setting the ReefKeeper Elite’s wavemaker setting can setup opposing pump cycles to simulate turbulent flow in your tank.

Manufacturer Info

Digital Aquatics Aquarium Supplies
Digital Aquatics was founded in 2004 and has quickly become the most recognized name in aquarium automation. Since the company debuted the original ReefKeeper 1 (now known as the RK1) in 2004, they have gone on to create some of the most flexible, innovative and cost effective aquarium controllers on the market. The revolutionary ReefKeeper Elite (RKE) was unveiled in 2008 and the affordable ReefKeeper Lite (RKL) came out shortly thereafter to appeal to more budget-conscience aquarium hobbyists. In 2010, Digital Aquatics released a reptile version, the HerpKeeper, as well as the aptly named PondKeeper.

Excellent product but...

I have used this product for many years and have maintained an accuracy that didn't exist before its purchase. The instructions have not changed much since I purchased this system six years or so ago. I live about 15 miles from where they began their business and back then they didn't have a layman's understanding for our hobby. To this day they expect us to figure it out for ourselves, engineers expectation.

Works as stated

The one thing is the instructions, they really did not come with any. So if you buy this item go online and read the PDF on the web sight. This will save you a big head ache. And there is no way to hook into the bus with everything plugged in. have to pull the i-temp bus plug to hook up Myreef. As for the product it does what it is meant to do. I had issues with my temp in my 90 gallon reef. With this thing i was able to set the temp, have it turn the heater off and kick a external fan on to blow across the top of the tank. PH probe shows my swings in the tank, witch is a good thing to know.All in all there are 101 ways to set thins thing up. And just added a ato to one of the switches with a lifter pump, works perfect. Would have given it a 5 stare if it had more detailed instructions, and a way to hook up my laptop with out having to pull the i-temp bus cable.

reefkeeper lite basic

Only had this unit up and running for 4 days. So far I'm impressed. Other reviews have stated the difficulties in the set-up process and I also had some problems, but only because this product has so many options. You don't receive any instructions for any of the detailed options. Downloading instructions from the Digital Aquatics web site is a must. At this time I am using the temp probe to control the temp on my 150 gal reef system. The temp never varies more than .1 of a degree. I also have the MLC module which when set up follows the monthly lunular cycle. Something to remember about the MLC, depending on the date this unit is set up and the phase that the moon is in on that date, will determine the brightness of the lunar pods. This could explain a few reviews that stated the lunar leds weren't bright enough. I use two pods on my reef, that were installed during a full moon cycle, they are very bright set at 99%. No need to add extras.

Hard to set up

The product is probably pretty good, if i can ever get it programmed. Bought it a week ago and still cannot get the programming right. Online instructions are pretty useless for simple stuff. Have called Reef Keeper and you can not talk to someone. All they will do is email you. If that is not clear you have to email back and wait. I did cal MD but they said that the could not help me. Not sure i would buy this product again. Too much work and no support.

Product support lacking

The product itself is OK. Myreef software is an absolute headache to get working and support from Digital Aquatics is non-existent. I'll likely switch to the Apex controller once I sell this unit.

Worth the hassle?

The product does its intended job after fiddling, tinkering and screaming at it for more than two days, I finally figured out how to set it up. No help from Digital Aquatics, their customer service is nonexistent . I will never, ever buy a product of theirs again!

Good, but not good.

Nice product but I have two plug per light and I have two lights. The power strip have 4 spots for plug but my plugs are to big to fit on the strip. I guess I am going to have to spend another $90 for another strip...... :-(
