- ATK Auto Top Off Kit - Neptune Systems
The safest standalone ATO on the market!
The Neptune ATK System comes with everything you will need to get an automatic top off system up and running within minutes. The ATK can be used on its own without the necessity of an Apex Controller, but if you have an Apex, the ATK will integrate seamlessly into your system and give you bonus features.
- Dual Optical Sensors
- Float Valve
- Includes PMUP and Tubing
- Strong Magnetic Bracket
- Multiple Levels of Safety
- Compatible with any Apex
The Neptune ATK can be used on its own, or in conjunction with any Apex Controller. Neptune's Auto Top Off Kit comes with everything you will need to have a functional and safe ATO system. The FMM module is the brain of the operation and has an indicating LED light along with an audible tone letting you know when anything goes wrong.
Dual Optical Sensors
Optical sensors are used by most of the top rated ATO systems, and the ATK uses two optical level sensors that control the overall function of the system. The sensors are pre-mounted into the magnetic bracket, with the lower optic being the primary water level sensor, and the higher optic acting as a backup sensor that will turn the ATK system off if necessary.
Adjustable Float Valve
Each ATK comes with a 100% reef safe adjustable float valve that acts as the last line of defense against overfilling. Float valves are very reliable and if water ever rises to activate the valve, the flow of water will be physically shut off saving you from a possible flood.
Don't think Neptune just stopped at sensors, and float valves to keep your floors dry and your tanks water level perfect. They included an algorithm that will monitor and learn how long it takes to fill your tank on average. After that is determined the system will never run for more than twice the time required to fill the tank. For example, if your tank typically takes 10 seconds to fill, the ATK will never run for more than 20 seconds, and if your system takes a minute to fill, it will never run for longer than 2 minutes.
PMUP Utility Pump
Each ATK includes the powerful PMUP that connects directly to the FMM module without the need for an additional power supply. The submersible PMUP fits is a variety of top off reservoirs and uses standard 1/4" OD Tubing (RO Tubing).

Would be better with better sensors By Mical on 9/19/2018Mical wouldn't recommend this product to a friendI have 2 of these set ups and had to buy "lab grade" sensors to make them work flawlessly. Good concept, bad chinese sensors
Worked until the sensors filled with water By mav1ms on 9/13/2018mav1ms wouldn't recommend this product to a friendI have had this running for just over a year. The optical sensors have both filled with water, meaning the sensors report closed. I have kept the sensors clean, removing buildup but never removed them from the unit itself. I simply brushed the sensors with a toothbrush.
With the sensors constantly reporting closed the unit doesn't function. When the sensors aren't filled with water it worked well... I have contacted Neptune support to find out about what I can do with the sensors. I refuse to replace sensors at roughly $40/sensor. I would strongly recommend looking at another product.
Junk By Sucker on 9/11/2018Sucker wouldn't recommend this product to a friendJust like every other product that Neptune puts out they let us work out the bugs. The sensors give bad readings. Had to turn it off! Can I have my money back?
Easy set up, working for months now no problem By Robert on 8/22/2018Robert would recommend this product to a friendI connected this to my Apex, put it in my sump, pump in the water jug and ran the wizard. Worked as advertised.
Another problem with this thing! By Charles on 7/31/2018Charles wouldn't recommend this product to a friend7 months using the ATK and my pump failed. This, on top of MANY, MANY, MANY issues with the unit giving false errors and needing to be reset. This is not what I would expect for the money spent. Choose something different than this item. Do yourself a favor.
Would recommend with caution By Ferrell on 7/3/2018Ferrell would recommend this product to a friendFor strictly an ATO with RODI it works fine. Do not try to use with Kalkwasser as the orifice on the float stops up and the sensors cloud over. Even with frequent cleanings I still get erroneous readings. Positive is it’s apex controllable.
I’m running kalk and have the float disengaged. Great concept but I’m going to come up with a mechanical float option as my third layer of redundancy
Don't use the float By aztankguy on 6/24/2018aztankguy would recommend this product to a friendI have two of these systems, one I've had almost 2 years and the newest one I've had just over a year. The one I have had over two years I do not use the float on and have not had any issues on. The newest one, I had room in the sump and tried to use the float on and the small orifice on the float makes it take forever to top off the sump and also seems to put too much back pressure on the PMUP and almost made it burn out. I've got it to where it works for the time being but I have a feeling I'm going to need to replace it a lot sooner then my original ATK PMUP. Beware of this because I feel like it is almost a manufacturer's intended flaw for secondary sales and mine started to freeze up shortly after the 1yr warranty expired. Just purchase a dosing tube holder and install it that way and you shouldn't have any issues.
Great System By jmfugett on 6/9/2018jmfugett would recommend this product to a friendI have had two of these. The first one failed. Totally my fault. I didn't set it up right. I didn't know Neptune had already provided a very slick, easy to install script for Apex users. I can't speak for using it stand alone, but I can tell you unequivocally that with an Apex this is rock solid and provides all the usual advantages of Neptunes controller. I have been using it for months and it is always spot on. I love the sensors. I, too, added one in the topoff reservoir and it is an excellent fail safe. It shuts off the pump if the topoff water gets too low (so the pump doesn't burn out) and immediately lets me know I need to refill. Very simple plug-and-play.
junk By birdman on 6/3/2018birdman wouldn't recommend this product to a friendsave your money and buy a spectrpure ato.
Works great for me By Steven on 6/3/2018Steven would recommend this product to a friendDon't understand what the prob is with others. For me it just worked. Installed it. Ran the task. Been working great for months. I have the optional sensor too for my water jug. it tells me when I need to refill it. great feature.
Great Auto topoff By leepink23 on 6/2/2018leepink23 would recommend this product to a friendI have had this for over a year with no issues, I would advise not to use with kalkwasser because things clog up easy. Took one star for the pmup being a little noisy. I do have it plugged into my apex which gives me a lot of programming options.
Super easy - three months without any issues By Stan on 6/2/2018Stan would recommend this product to a friendI know some are having issues - it was easy for me - and I do not have an Apex. Just plugged it all in and all I do now is add water to my reservoir. No troubles. I wish all my gear was this easy to set up.
No related items recommended for this product.
My rodi connects right to my sump under my tank. Is the pump removable on this unit and can i control shut off time without it?
I want to use this with a Nuvo Fusion 10. Would this fit in the return chamber in the back if I remove the float valve and rely solely on the two optical sensors?
With the float valve removed, the sensor block will fit in the back overflow area of your Nuvo tank. You could even add a third optical sensor if you wanted an extra backup.
Can I connect this directly to the Apex Jr or are there other parts needed?
The ATK is a completely stand-alone product with its own power supply, and if you want to connect it to your Apex jr., you'll just need an open Aquabus port and cable.
Will the siphon break that is included in the atk be sold as a stand alone product?
Have a great day!
I have the new Apex, is there a way to use the ATK without using another power adapter? Can I use the PMUP connected to my energy bar and how does that effect the ATO built in program?
Have a great day!
I'm going to run my ATO from my RODI reservoir. My reservoir is located in my garage. Only a wall seperates it from my aquarium so it is only 4 feet away once I run the RODI line through the wall. Obviously my reservoir will be higher than my sump. It will be 5 feet from ground level. Would I be able to use the ATK ATO for this type of set up? If not what do u recommend for this particular set up?
Can nuptune ato be used with kale reactor
Have a great day!
How long is the controller cable for the pump? Want to run it out to my RO container in adjacent garage, about 25 ft. away.
Have a great day!
Can I hook their solenoid up directly to my R.O.D.I. and forego the pump and resivoir.
Can this work with the Apex Jr?
How long are the leads from optical sensor to the fmm?
Does the siphon break allow the water flow to be sent to the sump?
With my "German" ATO I have to direct flow to the display tank.
Otherwise once started by the pump, the reservoir would be completely drained by the siphon effect. Bad!
Can the audible alarm be sillenced?
Is there a safety feature to shut off the PMUP in case ATO reservoir is empty?
Have a great day!
What's the maximum distance for the pump? I'd like to have a top off reservoir in another room. What are the stats on the pump? Is it just the utility pump? Can I use another pump with this system?
Hope this helps!
Is the magnetic holder and sensor unit sold separately for people who already have an Apex FMM?
Have a great day!
Is there going to be an option to purchase the kit without the FMM? I already have the FMM, so I don't need a second one.
My sump is lower than my ATO reservoir. Does this kit have a solenoid for my situation?
If you have your top off tank in another room are you able to program the pmup to operate from an EB4 or 8 or does it have to be plugged into the FMM
I have a 20 gal Fusion Nuvo nano tank. Will this ato work without the float. No room for that in the back of my tank
What is needed to mount the pump in the basement approximately 30-40 feet away?
The head pressure will be less than 10 feet
Hope this helps!
