Does the job By Felix on 10/9/2017Felix would recommend this product to a friendI do not have an intricate system so I don’t need much. Just to control temperature and monitor ph specially dosing kalkwasser. But I have issues with the my reef 2.0 program not recognizing my modules and not responding every time I click on a different icon. After much dealing with it I was able to program the essentials.
Awesome product By Dan on 9/3/2017Dan would recommend this product to a friendI've only really used one controller so I can't say a whole lot about. But it does what I need and a lot more then I was expecting. I'll always have a controller on all future tanks.
BRS is great but ReekKeeper support is VERY BAD By JayB on 8/26/2017JayB wouldn't recommend this product to a friend4 stars because it like what the unit does for me, love the automation, 0 Stars for support. I purchased a Lite for my first tank and all was good. Sure it has a basic menu driven input for the physical system with some practice it is easy to get to know. Using the computer interface from a laptop running win10 was easy enough. One trick i found was naming all the modules so you can see them better in the console. Anyway, decided to get the Plus for my big tank. Again everything as expected but the PH probe will not stabilize. So i tried to call support ... voicemail, sent an email. Not too bad 24 hours has a response with a question for me to check something and replied did this a couple of times 24hr turn around. They figured that it was a probe issue and then all comms stopped for days. Left voicemail, email nothing. I reached out to BRS to see if they could help. BRS was great the jumped in and tried to contact them. A few days later ReefKeeper finally replied that i needed to give them the invoice and my information and a credit card for a deposit. BRS already sent them the invoice so I resent it along with my information and followed the instructions to call to give my CC. Well support doesn't answer so chose sales and they answered ... go figure right? Gave them my card and he said he'd take it over the THE support guy. Days go by and support GUY sends me an email sales for got to give it to me i have it now can you send me your invoice and the requested information.... REALLY for the 3rd time i have sent them the information and again nothing for days.
Moral of the story, if you buy this and something breaks you will likely have to just buy a new part and forget talking to the company.
Cardo doesn't Recommend By Cardo on 7/19/2017Cardo wouldn't recommend this product to a friendThe provided instructions are on-existent. The downloaded manual is very, very poor. The controller simply doesn't work as described. Very frustrating purchase.
Happy By Danny on 6/18/2017Danny would recommend this product to a friendGreat product. Very happy. does everything I needed and more.
Get the basic or go all in on an APEX By Nathan on 6/8/2017Nathan wouldn't recommend this product to a friendI'm kinda old school. Not very techy. I finally decided I should buy something to control my heater and cooling fans- and then figured the extra power bar and probes of the plus system would be justified. I regret the extra purchase. This thing kinda sucks. I've spent way too much time trying to program it, downloading firmware updates, pulling wires out of sockets and plugging them into different ones. It's just - well, I kinda hate it. I still cant get the head unit to recognize the sl1 module so I still cant use my ph probe. The internet is loaded with videos all about this thing- and none have really done much to help me. It does replace light timers and monitor my temps and prevent over heating tank- I guess- but... I dunno. I'm not really happy with the purchase. BRS is a good company, but their videos haven't done me a lick of good when it comes to setting this thing up. They all just seem to assume that all the parts are all plugged in and talking to one another perfectly- which is the farthest from my experience. This thing in it's most basic form I could see being justifiable- but don't waste your money on anything more than that.
First controller experience By Bryan on 2/1/2017Bryan would recommend this product to a friendI have not been in the reef community very long, but this is my first time using a controller. It does exactly what I need it to do as far as heaters and skimmer are concerned. I was not looking for a complete aquarium controller that managed every aspect of my tank. I did not want to put all my eggs in one basket so to speak but overall pleased with what I got with DA reefkeeper. I didnt give it 5 stars because I haven had experience with other controllers to say this is the best thing I have ever used.
Timers don't function and no support By Anna on 1/17/2017Anna wouldn't recommend this product to a friendI purchased this product due to the great review by BRS TV but it hasn't lived up. Couldn't get the PH to calibrate, can't get the timers to work - as soon as I set a timer, it shuts off the power to the channel. NO ONE answers or returns calls at Digital Aquatics. I SOOOOOOOO Wish I'd paid the extra for APEX. All I have is power strips and they're not even surge protectors!
I like it By Dave on 12/11/2016Dave would recommend this product to a friendI use it with the BRS dosers and 2 part, water pumps, lighting (tank and sump), heater, fan and pH probe. It's easy to program with the computer or the manual interface. My only regret is that I didn't get it before I bought a pH probe/meter and heater/controller. I could have saved money getting the Reef Keeper first. If you want to attain stable calcium/alkalinity measurements, a controller makes it much easier.
Will always have a controller on my tanks from now on... By Chris on 12/6/2016Chris would recommend this product to a friendFor many years I was one of those guys with all of the timers and switches...everything "automated" in an old school fashion.
I finally decided to try one of these when they went on sale...very satisfied. I can't imagine setting up another tank without one now! Really cleans-up the setup and automates so many functions with one device. Programming both with PC and the pad interface are fairly intuitive and I found setup to be fairly straight forward.
NO CUSTOMER SERVICE!! By krazykelbs on 9/9/2016krazykelbs wouldn't recommend this product to a friendI purchased this product in Jan 16' starting off doing manual programming was fine until I wanted to program off my personal computer, then the nightmares began! The software would load onto the computer but not recognize the controller. Called the customer support, 9 time out of 10 you will not get a live person, forced to leave message. The one time I was able to talk to a live person he directed me to the FAQ web page. After viewing the page I come to realize that I was not the only person with this type of problem, and apparently not very many people were able to get the problem worked out! I contacted BRS to see if anything could be done on their end, THEY(BRS) has outstanding customer service! BRS did about all that they could do and said they would also try and look into having someone contact me to help solve the problem. if you only have a light or two and maybe a pump to control this would work ok, but if your trying to control a bunch of different things. . .check into a different brand and spend more money. In the last 3 months I would say I have left 12-18 messages and way too many emails to count, with only 1 reply and no resolve to my issue.
Well worth the investment By Dan on 9/9/2016Dan would recommend this product to a friendI have had mine for around 7 months and absolutely love it. It was a little difficult to figure out at first but I downloaded the instructions of of their website and was able to figure it out. It has worked very well for me and I haven't had any issues with it.
Ask a question
There is the SL2v2 salinity module available. Keep in mind you will need the Reef Keeper salinity probe as well. Feel free to let us know if you have any further questions!https://www.bulkreefsupply.com/reefkeeper-elite-sl2-ph-and-salinity-module-digital-aquatics.html
Yes, the two pb4 modules and slx count against the 4 module count. This kit will accept one additional module.
To add pH monitoring you will need to purchase a pH probe along with the SLX module. That will allow you to connect the SLX to your RKL system and then connect the pH probe to the SLX module.
Thanks for the question and if you have any others let us know.
All items on the site are designed and sold for use in the US and Canada. Feel free to let us know if you have any further questions.
This package will include the power controller x2, pH probe, iTemp Probe, SL1 module for pH control and the option to add on ORP. Feel free to let us know if you have any further questions!
I am unfamiliar with that setup but so long as it has the ability to use a 0-10v input line to control the LED's themselves then you shouldn't have any problems with the reefkeeper, though keep in mind you need the ALC module.
By using the APC module you will be able to connect Controllable Tunze pumps.
I am not aware of any other pumps supported by this module but it is possible that there have been adapters released to control other DC power heads.
I would also take a look at the ReefKeeper DCI DC Pump Interface. It may work for what you have in mind.
I am sorry I couldn't be of more help.
Have a great day :)
I actually have a controller running on my 16g here at the office. Despite the size of the tank, there is just some equipment you never can really get away from like heater, timers, etc which really makes a controller a great choice for just about any size aquarium and it would be a great choice for your tank.
