Very powerful device By David on 6/10/11

Bought this to automate my tank so that I don't have to monitor every aspect of my tank at all times. Fairly easy to install, you just have to access the support forum because instructions are not existent with this unit. Timers and function are easy to setup, and I'll be ordering double float valves soon to be rid of that manual task.

Have this controller set up on my 120G reef, I'm very happy with performance of this unit. It frees up alot of time for more important maintenance.

Lack of a pathetic excuse for the manual aside, this thing is AWESOME! Once I worked out the set-up and after only one mishap, it works great.

it's just about set it and forget it. i have a job that keeps me away from home for 24hr periods at a time. this left my wife who has no idea how to care for my reef tank in charge. now with the reefkeeper lite all of my important life support functions are monitored and controlled by the RKL all i need my wife to do now is to glance at the the display to make sure everythings in order and to top-off my ATO reservoir.

This controller is ok By David on 5/6/11

I have had a few minor problems with my RKL and Digital Aquatics has been a real pain to communicate with. Don't expect DA to be too much help with any problems you may have.

Good entry level controller By ZACH on 3/27/11

I bought this to automate, reliably, some of my tanks' tasks. I was impressed with the help at the DA online support forums. I was able to setup my metal halides, dosing pumps and heater without too much difficulty. I just wish that it came with 3 power strips instead of 2. The temp probe and pH probes work great. This is a system I will be upgrading/expanding in the future.

Good first aqaurium computer By Sean on 12/22/10

Bought this as my first aqaurium computer and i was very impressed! since i have bought the RKL i have since upgraded to the RKE because the RKE is able to operate more than 4 modules. if you are trying to decide between the RKL and the RKE and have the extra $$$ go for the RKE!

Fine, but don't rely on it for anything critical By Brian on 12/20/10

The control unit is very nice, seems well thought out and is easy to use.
However, the PC4 units are susceptible to a mechanical issue that can leave a
socket stuck in the ON position even though the controller thinks the socket is OFF. If you happen to have your heaters plugged into that socket you can kiss your
reef goodbye. Yes, anything made by engineers can have issues and that's why
a company needs good customer support, but with Digital Aquatics they require
the return of the defective part before they will take any action. Seriously, I want
this equipment out of my system.

Awesome By cjermont@yahoo.com on 12/8/10

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. The ph is right on I don't use the ORP as it's not need for my saltwater tank, but I use the switch port for my ATO and love it.

Good item once again, from DA. i wish they supplied better setup instructions and if it could only run off an apple computer.

so much more than just a timer By Karin on 10/21/10

Karin would recommend this product to a friend

When I got this I got it mostly because my husband thought my birdsnest of wires, power strips and bulky timers in my stand was a fire hazard! :o

I really just expected it to be sort of a fancy timer and now realize it's so much more.
I have it set up to drip kalkwasser once the pH drops below a certain point and I have been able to minimize my pH swings so much.
I also love the delay features and - of course- the timers. My heater is set on a controller as well and power to the heater is cut off if it ever goes beyond a certain temp -extra insurance because it's no fun to roast your inverts due to a sticky heater.

I needed a little tech support but DA was very responsive.

Didn't think I'd really need a ReefKeeper until I got one and now it would be hard to live without it. I got the #3 package that includes the pH and temp probes and a second power strip and it was perfect for me.
