Great unit for a Great price By Bill on 5/29/2012
Bill would recommend this product to a friend
Everything worked great right out of the box. Easy to setup and program. I have used this unit on a 2 gallon pico and 200 gallon progagation system and it did the job for both setups, very flexible on how it can be used. I did purchase an SL1 module to use it as an ATO, but that the great thing about this system, it is very expandable.

I don't know how I ever lived without this device. Now 2 PC4's later, most of my tank is controlled by this device. Takes a lot of the work and time out so you can do other things and enjoy your tank more.

The reefkeeper makes everything simple to control. It is defiantly easier to set up the controller with a computer. Once it is set up, it just works!! Patiently awaiting the release of the upgraded SL2 to be available so I can monitor Ph and salinity The only downfall is that I should have upgraded to the next level to get the extra controllers all in one package, but all in all, not a bad price for what it does out of the box!

Light and heat control By Nicholas on 4/13/2012
Nicholas would recommend this product to a friend
This monitor can do so many things, but I bought this version to get ready for summer, since I keep my house between 79-80; some sort of device to keep my tank in check so that it doesn't get so hot is going to be needed and this fits the bill. I haven't set it up with an alarm yet, but will soon so that it will let me know if that tank gets above 81.5. I was surprised to also see that the amps are registered through the computer too, good to know how much my heater really pulls so that I can be sure it will not overload the plugs.
This is a great controller By Steve on 3/26/2012
Steve would recommend this product to a friend
First off, BomBoms and James, don't blame your being stupid and inept on the reefkeeper. It did not almost kill your corals, you did. This thing is great. Controls my lights, my calcium reactor, and my temperature. I'll be upgrading to an elite, but for now the lite is simply awesome. I do wish it controlled more than just 4 devices, as my SL1, PC4, ALC, and second PC4 will have it maxed out and I want to add a net module. That said, it's well worth the money.

this is probably the best money ever spent on my tank. i don't think i could reef without it. programing on the keypad is not bad, but with the myreef software it could not be easier. everyone with a reef should have one.
under average product and bad support By BOMBOM on 3/11/2012
BOMBOM wouldn't recommend this product to a friend
i got this controller year ago, and i couldn’t be more disappointed.
the controller work fine if you are intending to use it only as a timer for your light(which you can do with 10$ timer unites rather than use this controller). but any other functionality like
- temperature control and reading
- PH reading and control
- collect statistics
- controlling chillers
- controlling fans
forget about it, anything except timers are buggy and always crash and give bad reading. i tried to contact the customer care, they were not useful at all, all what they will say is: calibrate the probs, restore the unit to factory default, or my personal favorite, wait for news software release.
i think getting other unites like the neptune is much better choice and better investment for the future/
Great Controller Once Set Up By Evan on 2/20/2012

So far, the Reefkeeper Lite L1 has been a very good controller so far. I did have a little trouble setting it up due to the severe lack of instructions that came with the Reefkeeper. Once it was up and running, it works just like Digital Aquatics claims.

Best deal around By Stephen on 1/25/2012
Stephen would recommend this product to a friend
Everything worked out of the box. Took off a star because this, and everything from Digital Aquatics has horrible documentation available with it. Its a crap shoot to figure everything out, and going on the forums and asking other owners is the best way to learn how to do that. To me, this constitutes a poor effort of QC on the part of DA. The product does work great. On a side note, if I had to do everything all over again, I would have opted out of the SL1 included, and instead got an SL2, since I do not does ozone, so do not need to monitor it, but would prefer the salinity monitor that comes with the SL2. An RJ-11 (6 prong) splitter is a must if you wish to have it constantly hooked to the computer. DA does not have any, but you can locate them online if you search for them.

I wish I handn't wasted my time and money on this controller. It almost killed all my coral twice and the suport for this controller is a waste of time. After asking you what you did wrong and asking you to reprogram it three or four times you might get to mail it back at your own expence just to get the same thing you had to start with. Mine had lost of things that didnt work with it.To save time Here is a list of thing that might not work with this controller.
and more or less anything else with a plug.

I had No idea how valuable controllers were until I installed them. This not only prevents problems from happening in your tank but saves hundreds in single purpose controllers, timers, undertank clutter and test kits. The only 2 problem I have now are a box of about $400 of equipment I don't need anymore and I get to play in my tank less...Great product for beginner to advanced reefers!

It's amazing how much the RKL can do, and now its hard to imagine how i ever managed without it. My only complaint would be the 4 module limit on the rkl, I only have one module on it right now, but i do plan to add more in the future, and it would be nice to have more expandability without having to get the elite.
Easy to Use By Tom on 9/17/2011

The RKL is a great product. It is easily expandable and simple to set up. I have mine hooked up to my 75g system. Right now im just running all my lights and heater of the system. I also added the net module which was a little hard to get set up but provide great functionality if you need to check on you tank if your out of town etc. Overall I think this is a great starter controller. My recommendation would be spend the extra cash and get the mid level package.
Does its job By Jim on 9/4/2011
Jim would recommend this product to a friend
Right now I'm using it to control the heaters, fans, and ato. Before I had the RKL on my tank my temperatures would fluctuate between 78* and 81*, now that I have the RKL on my tank the temperatures stay within 1/2 of a degree of 77.9*. Also topping off my tank was a nightmare due to loosing around a gallon a day from evaporation, now I just fill up the bucket every 3-4 days. It does its job really well and its also the cheapest controller on the market other than making an arduino diy controller. There's only one thing that bugged me when I got my RKL and that was the serious lack of an instruction manual.
Controls your stuff
Can protect your tank from heater malfunction
No instruction manual

At first I was a bit confused by the device. Honestly the user manual is non existent considering what this device can do! But it is great! Maintains my tank temp within +- .5 degrees F cycles my pumps for wave making, timer for my fuge light, standby mode for feeding. It has so many more capabilities, but for now this works excellent!

To control so many things with one thing is very nice. It has helped keep my temps rock solid, and getting real time data is very imortant. A little hard to get programed in the begining, but once you understand it, it is very easy.
You are able to control may things for your buck. Great deal.
NO BRAINER!! By ReefRacer on 3/4/2011
ReefRacer would recommend this product to a friend
I was looking at spending $100-$150 in decent timers form my light. With the 4 outlet PC-4 on the basic system, I was able to do the same exact thing and GET A WHOLE CONTROLLER for the same money. Since then I have added another PC-4 and the net controller. Ive got 2 of koralia evolutions on wavemaker mode and works like a champ.
The net controller allows you to connect the controller to your home network. With a spare wireless adapter in bridge mode, I was able to give the NET module wireless access. The built in Reef Keeper software for the NET is web based. Now view my tank stats from my iPhone and can even turn on or off any item plugged into the PC-4s!
NO BRAINER By Reef Racer on 2/7/2011
Reef Racer would recommend this product to a friend
I needed a good timer for my 2 t5 ballasts and a decent digital timer was around 35-45 each. Few a few more dollars I got the RKL and can control my lights and have one of my Koralia Evos on wave maker mode. And still had a plug for my heater.
Heaters are often over looked as area for fault possibilities. If a heater with a built in control dies while on (which is common), you're tank could cook. Whit the RKL, I plugged in a plain titanium heater to the 4th plug and let it control the heater on and off. If the heater breaks while on, the RKL will disconnect power when the cutoff temp is reached.
This is a no BRAINER purchase in my book.
Great and Easy to Program By Erik on 1/18/2011
Erik would recommend this product to a friend
Being an Energy Engineer, I love to tinker with electronics. At the same time, however, I have no patience for ones that are difficult or tedious to program. The RKL system is extremely straight forward. I have it running my heater, T5HO's, and two Hydor Koralia Evo powerheads.
Just note that small motor loads such as the powerheads must be plugged into channels 1 and 4 on the PC4 module. The solid state relays on channels 2 and 3 will stick (latch) in the ON position if small loads are connect. No biggie. I just connected my 300W heater and my 2x54W T5HO's to Ch2 and 3.

I bought this product and the SL2 module. Everything works great, although I find with a SL2 module, the plugs, and the net module....you might want to also consider upgrading to the elite. The Lite only allows 4 modules.
Other than that I use it to do heating, dosing, PH monitor, lights, and more. This makes the 4 plugs go really fast.
I only gave this 4 stars for performance because I found that once when I was playing with the settings, the whole system reset reset. This has only happened once, and probably fixed in a firmware update (haven't updated firmware yet). Other than that this is a great deal.

I love this Device! I use it to control everything. The heater option allows me to keep my temps with in .1 Degree and that's way better than trying to set it. Also I use an old heater that use to burn up and set the default to off and the RKL make this device work flawless. I also love that it can tell me amps as well as graph anything I want.

I have since upgraded and have PH and Salinity probes too, knowing exactly what your tank is doing all day and night when you are not there to monitor it.
