- 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).

Easy to set up By Charles S. on 3/11/2019Charles S. would recommend this product to a friendI don't have an Apex yet but i think i will some day so i chose this for my ATO. Super easy to install. Just plugged everything in and put it at the level I wanted my water in my sump. It has been going for a few months now with no issues.
Saved my bacon By Justin on 2/28/2019Justin would recommend this product to a friendI made some boneheaded change to the configuration (from default settings) of the ATK in my Apex and the water kept running overnight. Thank god for the float valve on it. When I woke up, my phone showed an alert message and when i went to the tank, the water was above both sensors and my solenoid was wide open - the float valve was the ONLY thing saving me from divorce!
Wondering about these reviews By ZimzZoaz on 2/26/2019ZimzZoaz would recommend this product to a friendJust left a review on the COR. Bunch of negs there unwarranted if you ask me. So I thought I would check out reviews on some of the other neptune products I own. Again. Can't understand the issue here. Bought one of these on Black Friday sale. Aint nothing to do but plug the stuff in and follow the directions. Did that and its been topping off ever since. I use one of those office water bottles for my ATO reservoier too! hahaha.
Works. Thats all I know By José on 2/20/2019José would recommend this product to a friendI plugged it in. Followed instructions. Had one prob. Called support. Quick answer and its been running fine since that time. Thank you BRS.
Been working great for over a year By Tim on 2/15/2019Tim would recommend this product to a friendDon't know what all the issues are from others but mine seems to just work. Never did anything to it since I ran the set up task.
Great feature list, but the execution falls short By Brett on 2/15/2019Brett wouldn't recommend this product to a friendI have never been so happy for a product to fail. It did not fail due to the craftsmanship, but I had a skimmer overflow and spray mist everywhere and the FMM got too wet and it died.
However, I got so very tired of all the alarms. If I had my hands in the tank, which changes the water level in the sump, I would get 15 text messages in the span of about 10 seconds. I would have the same thing happen if some water splashed on that high level sensor. Which is great having your phone go nuts while I'm at work. I wish I could post the screen shots, because when this thing goes into alarm mode (which is a lot of "crying wolf" scenarios) my phone would be filled with text messages. It was a weekly occurrence where I would have easily 40-50 text messages a day from this stupid thing.
I give it two stars because of the feature list and the PMUP worked well for me. But now that it failed, I am going back to the aquahub top it off kit for 45 bucks that previously worked for 4 years without a problem. Still using the PMUP with that system.
Garbage By Steve on 2/12/2019Steve wouldn't recommend this product to a friendGarbage..... crap... useless... and good luck returning it.
Thru the pump in trash. Doesnt work... dont buy.... zero stars
NEPTUNE Auto Top Off Failed Out of the Box By Needs Improvement on 2/12/2019Needs Improvement wouldn't recommend this product to a friendNot impressed with the water pump that Neptune included in the ATO system. I pulled it out of the box to test the system. The water pump came on but could not pump the water through more than 12 inches of head pressure. The box claims it can push the water to 14 feet of head pressure. Neptune has more design work to do!
Works good as long you know how to troubleshoot. By Rick on 2/11/2019Rick would recommend this product to a friendThis works good but its complicated and you must know how to troubleshoot your Apex system. I had turned off the Port 3 which is for the RO reservoir sensor and removed it from the ATO configuration and now its working fine. Many times, when it stop working, I thought the unit went bad but its not. When you are having problem, open a ticket with Apex, as this requires troubleshooting by an Apex technician which they can remotely connect to your system if its connected online through Apex Fusion.
Tech support one star By Steve on 2/4/2019Steve wouldn't recommend this product to a friendThis review goes for anything Apex- Neptune.
Ordered this Atk and pump would not work. I was able to get it to turn on when installing it but it would not pump water.
If you read reviews on this pump where brs sells it by itself it has 2 stars. Its garbage.
How I fixed it- I used the program code to the Atk to a seprate outlet ato pump. I'm not using the 24volt pump.
I called brs and Tech support from apex sends you a to do list including taking pictures, and taking pump apart! Really? How about just send me a working pump? I'm not taking apart a brand new pump...
I also bought a apex Neptune 2 inch flow valve(99$ for valve) and it dont work.
I called tech support and they said since it was installed they wont give me my money back.... ummm how are you to test these items without installing them?!
And they wanted me to take the flow valve apart as well! How about you all send me a working 100$ valve and you can take the broken valve apart? I didnt purchase items that said "could be broken or not functional till you take apart"
Funny thing is there is quality control stickers on them!
Wont be buying this crap no more. I'll eat this money this time. Wont happen again.
If you buy anything from apex or brs.. you better double check thier return policy.
As a whole... I like brs... love the videos but their tech support seem like they strong arm you. That's not right...
Error send and not able to reset By Luis A on 1/31/2019Luis A wouldn't recommend this product to a friendI have running for few days and stop working , trying to reset the system but doesn’t work at all again
Wasted money By Pat on 1/13/2019Pat wouldn't recommend this product to a friendSensor's were not working Try to call company not impress with The lack of help (apex support )
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!
