- 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).

Great when it works! By Doc on 12/8/2017Doc would recommend this product to a friendI had the JBL system perform flawlessly for a few years running a small cobalt pump in a 55 gallon reservoir. I have a 250 gallon mixed reef and lose about 2 gallons of water per day. I was going on a trip and became intrigued with tis ATK as I love my Apex JR. Three days into the trip I get an alarm with no one to check on it. Find out the Pump smooth out failed. Luckily I had enough water in my 75 gallon sump so that the return had enough water. BRS promptly sent a replacement pump.
Then I started having alarms constantly. I called Neptune and they were helpful but couldn't solve the problem. I found it today and this is why I am sharing this. The opening where the inflow connects to the shut off float is pin hole thick and will clog easily. I found a large grain of sand and cut the flow. The unit times out after five minutes and sends an alarm. I drilled the hole out to 1/8 inch and it is now working. You might try this simple solution if your Apex is reading "open" on sensor 1 and the alarm goes on.
Over priced, false alarms... By Steven on 11/26/2017Steven wouldn't recommend this product to a friendI have had this unit for 2 months now. Almost every day I have to reset this unit. Today I found that the line nut that holds the tube onto the unit leaks. When this does this it leaks on the optical sensors and the unit thinks it has overfilled. I fixed this problem by disconnecting the line and just running the line in my tank. This disables the float valve. I would not buy it again.
So easy to use By Jason on 11/22/2017Jason would recommend this product to a friendI picked this up on sale. I just installed it. I could not believe how easy it was to install. Thanks BRS!
Running in stand alone for now By Ferrell on 11/20/2017Ferrell would recommend this product to a friendI’ve only been running for a week now and so far so good. I did have a problem with the push fittings coming loose twice (probably didn’t push/pull correctly). Didn’t get the exact placement I wanted because of the huge float but may turn it around and try the other way. And lastly the he pmup is a lot louder than the rest of my system and wasn’t expecting that.
Have not had any troubles. Worked well, keeps sump time fill line.
I do have a RO varios return which comes with a low water switch directly to the controller as added backup for my pump.
I’d give the overall rating a 7 at this point
I am disappointed, Piece of Junk. By JimFuller on 11/7/2017JimFuller wouldn't recommend this product to a friendI have had this for two months. It is error mode more that working. I have cleaned the sensors, plugged and unplugged cables, tested the pump. It still does not work reliably. If this is the example of Neptune's products, I will not buy another piece. I do not recommend it.
Great Idea, Poor Implementation By David on 10/31/2017David wouldn't recommend this product to a friendWhen it works, this is an excellent ATO system with the added bonus of being able to add leak detectors and flow sensors. When I initially set the system up, I was going back and forth with Neptune’s tech supportive to a faulty sensor. Ultimately BRS was the one to rectified the situation. Now about 2-3 months later and now one of the sensors are bad again. Due to the size of my return chamber I had to run this system without the float, and my worste fear is coming home to find both sensors failed in the open position.
Now I love the thought process behind this system, but it almost seems like this was rushed to market prior to adequate testing.
This and other experiences with Neptune has showed me that in terms of overall monitoring and controlling, Neptune Systems is great, but anything else, stick to trusted brands.
I am currently planning a 300g aquarium (about 375g system) and will definitely use the osmolator for my ATO needs.
Worked like a charm By Casey on 10/3/2017Casey would recommend this product to a friendFollowed the instructions on the card to install, ran the task in Apex Fusion. That was it. It just works. Had if for about a month now.
Great ATO - wicked easy to set up By Jeff M. on 9/25/2017Jeff M. would recommend this product to a friendI got this because I have an Apex (with my own DIY ATO) already but I wanted an ATO for my QT that is located in my garage (no Apex there.....yet). Went together super simple. Haven't touched it for five weeks now. I really do not know what these other guys are doing . So simple. When I upgrade to the new Apex, my classic will go to the garage and connect up to this.
High expectations, disappointing performance By tlk2marty on 9/4/2017tlk2marty wouldn't recommend this product to a friendI have owned this product and implemented for just over a week, and very disappointed with the results. Building my system toward Apex automation this was a component I needed to upgrade. But I have found ATK to fail frequently. Despite following instructions, I had trouble getting the hose to hold in the pump coupling, and was advised by Neptune support possible it was pressed too far into the elbow on the unit in my sump. Still, this did not stop me from alert conditions every 24-36 hours which halted operation until I could reset. Now the product still fails on alert conditions and without the Apex controller I have no idea why nor any way to determine. It does beep, but that was not helpful.
In features the product seems well designed and modern. And I like the direction I was going for automation, but I need the standalone to work while I get there. It is expensive for the poor performance. First level support from Neptune was not helpful, but the escalation gave me good suggestions/feedback, though did not solve the reliability of the product. For $200 I have much higher expectations. I am dumping the solution and replacing with the Tunze Osmolator 3155 recommended by BRS and other hobbyists I've talk with about my troubles. I need consistency and reliability. Maybe when the kinks work out the ATK will be a better product, but it is not the product for me today.
Perfect By RBG on 8/9/2017RBG would recommend this product to a friendEasy instal, redundant safety features. Worked well right away and still does,
Mixed feelings on this piece of equipment By Randall on 8/8/2017Randall wouldn't recommend this product to a friendFirst, the good:
You can tweak the Apex programming to give you very granular auto topoff control. For my 100 circulating gallon system, a Defer time of 002:00 and a Min Time of 030:00 results in 10-20 seconds of auto topoff every 30-60 minutes, which keeps the salinity very stable.
The system comes with a siphon break valve, designed for systems with elevated RODI containers like the Red Sea Reefers. It works fine with pure RODI water (if a bit noisy), but I have no doubt it would clog quickly with kalkwasser-infused topoff water, as others have experienced; Neptune really should mention somewhere that this is not recommended.
The default Apex programming is pretty bad, at least by my standards. You may need to tweak it considerably to provide small incremental topoffs rather than large disruptive ones on your system.
If you don't have an Apex controller, best not to buy this system. The standalone features and limited configuration options are not attractive.
The 'high level' optical sensor is pretty close to the low level sensor. If you use the high level sensor for an alarm, be prepared for endless false alarms if you sometimes slightly overfill your sump, for example in preparation for acclimating new arrivals.
The really bad:
After 8 weeks, my low level optical sensor failed in the CLOSED state, and started leaking rust or something even more toxic. The contamination was bad enough, but the closed state meant that the ATK was going to think that everything was just fine as the water level went down down down and the return pump eventually stopped. Good thing I monitor my system obsessively. And that I had a spare optical sensor. From other people's experiences with this device as well as with the DOS DDR containers, it seems like these optical sensors are not really up to long term use in harsh chemical environments.
Best Ato By Inks on 8/1/2017Inks would recommend this product to a friendI've used tunze but I like this one better
Installing the Neptune ATK is pretty simple especi ...

No related items recommended for this product.
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.
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.
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!
Have a great day!
Have a great day!
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!
Have a great day!
Hope this helps!
Have a great day!
The head pressure will be less than 10 feet
Hope this helps!
