    Comments: I was a bit intimidated initially, but within a few hrs of looking thru sample programs on the Neptune user forums, and also a few emails with their support, I got fully familiar with the full capability of this controller. Neptune Support replied with a few hrs both times. I have a 205gln Planted Discus tank with LED lights, CO2, and this controller has definitely made tank care easier, and more consistent. Autofeed cycles are setup, lights ramp up and down, CO2 is pH controlled but off at night, UV is on for 12hrs a day, powerheads are on for 6hrs a day for circulation etc. The pH control is very fine grained and I think due to that, even with less full strength light(2hrs a day with 3hrs of ramp up and ramp down) plant growth is excellent with lots of pearling, maybe even more than before. Web interface is great too. I setup a few maintenance modes which I select from my Android phone. I should have bought this much earlier.

    Comments: Awesome product so far. It is difficult to setup initially but once you learn and understand the code expressions then the sky is the limit. I was going to give it 4 stars due not so friendly configuration but saw a few previews of Fusion (their future web base configuration) which is more user friendly, hence they deserve all the stars.

    Comments: Awesome unit, have to be a little tech savvy or you can program them to flood your floors like the other guy did! : ) Get some help from Neptune and the support forums and they will be a great addition to your tank! Programming is not THAT hard it's just different. The forum's have post where you can just copy and paste onto your Apex profiles!

    Comments: The product can be very intimidating and frustrating especially to people who are not computer savy. A lot of reading, researching, and asking. But once you are able to figure it out, you will see the great potential on how to make your hobby easier and interesting. Customer support is responsive and as able to help me out a lot. The same as the community forum. Expert members are there to respond to questions and help out. Maybe before you actually purchase, start reading the manual and go to the forums so at least you will have an idea of what you will do. All in all I love the product. I just wish it is more user friendly especially for people who are not computer savy.

    Comments: this unit flooded my home 2 times i lost 15 fish because it shut off essential pumps it turned off a heater it ran my kaulk wausser until it was empty, killing 8 SPS coral it is pure garbage good luck finding someone to help you set it up it took customer support over 1 1/2 hrs. to help me get this unit online i have yet to get any other help its been 3 weeks. all yeah the energy bars don't power on they cycle power that is a deal breaker the unit does not have the wireless ability so it has to be hardwired if you have a 50 foot run you will have lag time which can throw everything out of wack.

    Comments: I installed the system in about an hour. After years of headaches and the frustration of terrible support from the other controller system that I had, my only regret is that I didn't get the Apex sooner. I had some questions when I installed it, and I had answers to my e-mail immediately. I had traded four e-mails back and forth with them in a couple of hours, and my questions were answered and problems solved. The ease of customizing the home screen is great, and the variety of control options are amazing. I have the system controlling 3 Kessil a360's, ATO, heaters, sump lights, UV, reactor, cooling fan, and it is perfect! The quality of the components is outstanding, and all parts arrived here when promised. The system has been running for a week, and there have been no errors.

    Comments: Well I had to ask myself a dozen times is this what I needed or wanted and I made the right choice by making the purchase of the Apex controller. I have had the controller for about a year now and I am still fine tuning and adding probes and modules to control how pumps and sensors work on my 60 gal. Tank. I control feeding cycles through my computer, I monitor my tank for leaks off sight through my cell phone. I control heating and cooling, water top off with the push of a computer key. I have a read out monitor that tell me my aquarium health.

    Great Controller

    Comments: This is a great controller. If you have a remote sump/fish room, I recommend getting extensions for the Aquabus cables and an extra EB 8. I was able to daisy chain accessories to get to where I needed to go, but I did order another EB 8 and a 15 ft extention. For the extream hobbist that never stops expanding their system, this is the perfect controller. And the programing is not too difficult.
