- 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).

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.
Stay away By Kyler on 6/1/2018Kyler wouldn't recommend this product to a friendTalk about over complicating a simple task. This thing has way to many errors and issues. I am serious stay away it will kill your corals!!!! Constant issues and having to reboot this sucker due to errors. Don’t dare leave my tank because 2x a week it’s having issues. Neptune tells you it’s user error (thanks Neptune for the poor customer service) but read your reviews Neptune. Your product is so crappy and so expensive
ATK By MSG on 5/6/2018MSG would recommend this product to a friendLove this ATO it works so good I bought another for my new build, my current unit has been running flawlessly for almost a year
Good with apex By TPack17 on 5/5/2018TPack17 would recommend this product to a friendAs a stand-alone it has issues. Stop your pumps or do a w/c and you will get an alarm. You have to unplug and replay and it has to relearn again. With my apex my other one works fine. Get a lot of errors stand a lone.
Constant failures, Neptune always blames user By Christopher on 5/1/2018Christopher wouldn't recommend this product to a friendI'm sick and tired of calling Neptune to report that they have sent me broken equipment just to have them tell me it's my fault. It seems they never want to take responsibility for their broken equipment and failed engineering. It's disgusting and I'm sick and tired of them. With this industry needs is another company to come in and put them out of business with something better. This ATL kit constantly fails as constant issues causes more problems and instability than I would ever have they just didn't use it. I've had several tickets for support internet tune but all I get from them as excuses and explanations for why it's my fault they're bad engineering doesn't work. I can't recommend this product to anyone and I can't feel like you're me figure out how to get a replacement from them.
Sensors needed to be replaced within the first few months By JC on 4/30/2018JC wouldn't recommend this product to a friendThe low sensor started to corrode, so Neptune replaced it. Repeated pump failures where I had to restart the ATK. High level sensor then failed after I did a water change and it was exposed to some water (has been exposed to water less than 10 times since I bought this). This may all be worthwhile if you were paying $50, but not at $200. Neptune is now sending me a second sensor.
NICE ADDITION By NOMAD on 4/18/2018NOMAD would recommend this product to a friendEasy Set Up, works just fine. I had to install a baffle in return area to reduce surface turbulence. Alerts multiple times when water level gets to high during maintenance. But that isn't a bad problem to have, you will know its working.
troublesome By robert on 4/17/2018robert wouldn't recommend this product to a friendPain in the a$$ if you dose anything, floods from siphon break after cleaning due to SB cloged and dumping 2 gallons of top off with kalk
Needs several adjustment after water changes, And Just forget about Kalk in topoff, you WILL KILL your corals!!!!!
This thing works against water stability
JUNK SAVE YOURSELF AND YOUR TANK By Neptunedeeznuts on 4/12/2018Neptunedeeznuts wouldn't recommend this product to a friendLet me start with I have lots of Neptune products but this one is JUNK. First issue I had was the module just started blinking and wouldn't work out of the blue. I emailed support and got little to no help. I disconnected all the wiring and reset the module with the wizard. Started working thought maybe a freak glitch. Next incident came home and my skimmer had overflowed and the top off had kept running kalking my tank. I did a water change and figured it was the run time. I shortened the run time and did a greater than to off code to prevent it happening again. Then on a Saturday I'm sitting on the couch and the pump starts and didn't shut down. I spring off the couch whipping the slider into the off position and it wouldn't turn off. I had to unplug the power to get the pump to shut down. Reset again and it worked fine for a week. Wake up the other morning to the sweet revving sound of a dry reservoir and a pump out of control. Like the time before the slider in the off position like I coded. However the pump racing non stop until I physically unplugged it. Once again emailed support to a screen shot of my log showing the slider in the off position. Told them that yes it was in the off position but the pump continued to run. Response was did you install the syphon break. WHAT.... don't you read good gravity syphon has nothing to do with the pump ON when it should be OFF like the slider indicated. Do yourself a favor and get a Tunze like I should have. How come Neptune cant customer service like BRS!!!!! FOR THE MONEY THEY SHOULD!!
Works good By Jason on 4/11/2018Jason would recommend this product to a friendReplaced tunze that just quit working after only 2 years. Have it connected to the apex and it works great. Pump is a little noisy, but not annoying.
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!
