Say Goodbye to Manually Testing for Calcium, Alkalinity, or Magnesium in your Reef!
The Trident is an automated testing system that regularly tests alkalinity, calcium, and magnesium in your saltwater aquarium — and then communicates this information to your Apex so you can get alerts, and change your dosing. When combined with the DOS (available separately) it creates a fully automated system for the proper dosing of supplements, maintaining them at consistent levels.
- Automatically performs Calcium, Alkalinity, and Magnesium tests
- Includes 1-month of reagent
- Combine with Neptune DoS for automated dosing
- Programmable alerts for out of range parameters
- Data is graphed for easy to comprehend tank stats
- Can be set-up and integrated with your Apex in less than 15 minutes
- Empties used reagents and sample into an external vessel (not included)
- Up to one month of testing before reagents need changing; based on 4-Alk, 2-Ca, 2-Mg tests per day
How It Works
The Trident is a self-contained automatic titration colorimeter. That’s quite a mouthful, for sure, so let’s state it as simply as we can. The Trident is basically automating what you (and top scientists) do already when you test your water, that is, perform a color changing titration and interpret the results.
On a scheduled basis the Trident carefully mixes its reagents with a small amount of sample water from your aquarium. While doing this, it is measuring (titrating with a precision peristaltic pump) the amounts of each that are necessary to reach an expected color change (determined by the electronic colorimeter). When it finishes the titration, it sends this sample/reagent fluid to your waste container. It then interprets the results of that test and logs the value into your Apex.
Easy Plug & Play Setup
From the box to testing in under 15 minutes! Unlike other testing systems, there are no reagents to mix, tubes to cut, or pumps or probes to calibrate. Simply plug in one cable, two tubes, and run the setup task on the Apex Fusion mobile app — it holds your hand through the installation with helpful videos along the way.
Consistency & Precision
The Trident tests with a precision of +/- 0.05 dKh for Alkalinity and 15ppm for Calcium and Magnesium. This is better than humans can do consistently with every hobby-grade test kit on the market.
Understand Your Reef Tank Link Never Before
When you start getting the regular data coming in from the Trident you will be amazed at the things you can see happening. The daily light cycle swing on calcium carbonate uptake. A salinity drop by watching magnesium. An out of sync dosing of calcium. This increased understanding ultimately helps you maintain a better, more successful reef.
You can set up your Apex to alert you, or take immediate action(s) when a parameter falls outside of the safe zone you specify. As just one example, you might be dosing an Alkalinity solution and a misconfiguration could lead to overdosing of your tank. The Trident will catch that, alert you, and give you more time to make that correction before its too late and to save your aquarium. The data from the Trident can also be used to turn on and off other devices (like dosers or solenoids) to protect your tank even more.
Ultimate Stability with the Neptune DŌS
The more stable you maintain proper levels of Alkalinity, Calcium, and Magnesium, the better your corals will grow and thrive. But coral uptake of these supplements often changes and requires us not only to perform more testing but also seems to put us in a never-ending state of adjusting our dosing levels.
The Trident, when paired up with one or more of our DŌS systems solves this problem with Automatic Dosing Control (ADC)
When configured on the Apex, ADC will take the results it receives from the Trident and uses them to gradually turn up or down the amount of additive your DŌS delivers. But, don’t worry, we have built this feature with safety in mind. With ADC you set your target value and your starting dosing amount and ADC will only tune that dosing level +/-35%. If it takes more than that amount of dosing to keep your aquarium at your target value, then the Apex will stop ADC, revert to your starting dosing amount, and alert you that you need to manually adjust your dosing level. Then, ADC can be re-enabled and it will continue to guide your DŌS so that it keeps you as close to your target value as possible.
It is possible to use ADC for all three tests – Alkalinity, Calcium, and Magnesium. You can also use one test value to adjust up or down more than one additive delivered by the DŌS (i.e. Triton system).
Simple Reagent Changes
When using the default testing schedule of four (4) alkalinity, two (2) calcium, and two (2) magnesium tests a day, the reagent stored inside the Apex will last a full month. And adding new reagent is super simple — just slide out the drawer, remove the old bottle(s), and replace them with new ones. If you desire, you can also run a calibration session with the included calibration standard.
The cost of reagents and the recurring cost is a valid concern for a hobbyist considering the test kit or automated system – and we designed the Trident with that in mind – keeping those costs as low as possible. Reagent comes in 2-month kits (based on the default testing schedule of 4-Alk/2-Ca/2-Mg per day). These kits include two bottles of Reagent A (changed every month), one each of Reagent B and C (changed every two months), and one bottle of our calibration seawater sample. The reagent kit has at least 240 alkalinity tests and 120 tests each of Calcium and Magnesium. These two-month kits are priced at just $44.95 in the U.S.
You will hear the Trident operate from time to time if you listen closely or you have a super-quiet room. And, as compared to other automated testing systems, it is several dB quieter. While inside your cabinet along with your other equipment, you will likely never even hear it.
Alkalinity Precision - +/-.05 dKh

*The included reagent is the actual 2-month reagent kit, however with initial setup of the Trident, a small amount of reagent will be used, which will result in about 45 days of reagent remaining (which can vary depending on how many times a day you test).
Worth Every Penny By todd on 7/6/2020todd would recommend this product to a friendI got this the day it was released and couldn't be any happier. Even though I think doing a couple test per day would work (maybe not for the unit) I'm OK with the number of test. For the amount of livestock I have, $200/yr is worth it.
I haven't had any issues (knock on wood) as far as lines leaking, bad test, calibration issues etc. I pretty much let it do it's thing and then change reagents and calibrate. My Mag and CA stay pretty constant and when I calibrate it seems good as well. I haven't cross checked it for "accuracy" with other test kits but everything seems to be doing well. If it is between buying the "next big thing" and purchasing a trident, I will recommend the trident. STABILITY is key to a successful reef.
Need more work By Michael on 6/14/2020Michael wouldn't recommend this product to a friendWorked great for the fist month and a half, after the first exchange of reagents, that’s when the problems started no sample water, bad test A, and C the list goes on. All you can do is a restart/reboot witch does not work all the time. Hope fully they can fix these bugs soon; for this price point it should work better. Great concept I wish it worked better.
Works like it should By Brett on 5/26/2020Brett would recommend this product to a friendHaving a nano tank, I've been a little anxious about keeping my tank solid and stabile. Especially since I live in New York City and I'm in and out of the apartment. The simple design and simple way it works, is everything I needed for piece of mind to finish adding corals to my system.
It Simply Works By Neal on 5/10/2020Neal would recommend this product to a friendI got this to test my water while I go away on longer trips for work and vacation I waited a month to write my review and simply put it just works. I have changed out the A reagent now and got a spot on test checked with my red sea kit. Each time i've checked with my red sea they've been extremely close (down to degrees of accuracy). I love it and am glad I got it!
Simple design, expensive reagent By Jeff on 5/8/2020Jeff wouldn't recommend this product to a friendAlk measurements are solid but over time calc/mag measurements can be questionable (esp if reagent runs low or unit has age). A unit that has been running over 10 months now does not hold calibration past a month which requires re-calibration and wasted reagent. It is rare to get more than 1.5 months out of a 2 month reagent kit at the lowest testing interval. Cost of reagents are high and will add up over time. Unfortunate they do not offer an alkalinity only version and alk only reagent refills.
Automation is the Bomb...No more water test weekly or daily By Dave on 4/27/2020Dave would recommend this product to a friendThis unit has been out on the market for a while now. Over a year as far as i remember. I finally jumped the gun and got one. I was waiting for the Xepta but its not even out yet in the U.S. and probably wont be out for a while. This unit is built ok. Its not cheap cheap plastic. But it doesnt look like it could handle being dropped on the floor.
Setup was pretty straight forward. Took about 30 mins.
I doubled checked the values from the trident with my Hanna Check and the Red sea test kit for Ca & Mg. Its pretty close. (I didnt expect it to be exactly the same but its close enough). I will continue to spot check it here and there but This machine is well worth the money. As we all know, everyone has a life to live and doesnt have time to test every day or what not. Now if you have a Calcium reactor, I dont know if it will be worth it to get this machine because your alk and calcium levels should be stable for the most part.
But given the amount of money some reefers invest in this hobby, this is definitely worth the investment. Especially if you dose 2 part alot. Dont focus too much on the values. Focus on the overall values and stability of the values. I wasnt look for it to be 100% precise. But it tells me if the values are stable and that i dont have swings.
Note* the minimum test for alk is 4 times per day and for Ca & Mg is 2 times per day.
Also NOTE* make sure you stock up on Reagents. Neptune says 12 months max. Because as of this date 4/27/2020 we are dealing with COVID 19 and it is literally hard to get the reagents. I Live in Central florida and WWC and TSA dont have em. They are being released sporadically on BRS and Saltwaterquarium.com as well.
You dont want to run out of reagents. Thats like having a Ferrari but no Gas. Lolz
If your on the fence. Get it. Its well worth the money. And follow the darn Directions. Its not that hard.
Great concept - poor reliability and support. By Mark on 4/13/2020Mark wouldn't recommend this product to a friendAlk seems ok, cal and mg are way off and support is worthless. I stopped dosing for a few days to baseline consumption before switching to AF dosing. Both Hanna and Red Sea confirm a drop in all parameters as expected. The Trident shows a small drop in MG and no drop in calcium. Morgan at Neptune says the Trident is working fine. Crazy bad support. Typical Neptune. Hoping another option comes along.
Accurate, no hassle testing with a caveat By Jason on 4/13/2020Jason wouldn't recommend this product to a friendAs far as the equipment goes, I'd give the Trident system a solid 5 stars. The tests are always spot on when double checking results, and their is almost zero work once calibrated. But the major problems are with the reagents. They are constantly out of stock, and don't last anywhere near the time advertised. The machine must run 4 minimum tests per day to maintain calibration, which not only is unnecessary, but a waste of reagent/money. I assumed having a "manual" option setting testing up daily or every other day would have been possible. I don't need my alkalinity tested 4x/day. No one does. At $600 for the unit, and closer to $300/year in reagents, I just wouldn't recommend this product, unless you really have the money to spare.
Expensive solution for testing By Mark on 3/19/2020Mark would recommend this product to a friendHave had the trident for approximately two months. It is simple to setup, and once setup requires no tinkering except for replacing the reagents. Coupled with the DOS, you can dial in ALK and CA to your liking and it stays rock steady.
Two glaring problems though:
Reagent supply is insufficient for the demand, its also costly and does not last as long as it says.
Secondly there is no ability to set manual testing times. The minimum testing is 4 times a day for ALK and 2 for Mg and Ca. This obviously uses a ton of reagents, but there is no way to just do it once a day or twice a week. You can only test on the set schedule (which does go up to 24 times in a day if you want that.) Hopefully in the future we'll be able to set our own testing times and save money on reagents.
Really a game changer By Samuel on 9/6/2019Samuel would recommend this product to a friendI’ve had it setup for a few weeks now. Install was very simple so long as you follow the instructions.
My readings are a little wavier than I hoped but definitely as good as testing manually and I’m able to tweak my DOS pumps whenever I feel like which is fantastic.
I ran 12 tests/day for 48 hours, then 8 for 72, and now I’m at 4 tests long term. Really helped me to dial everything in.
I wish the drain tubing was just a little longer. I think they guessed at what most people would want and since my setup is non-standard, I’m not knocking a star for that.
I do think the shape is a little odd. I feel that they went for style with the design and I wish they had gone for function. A simpler more rectangular shape would have been sufficient. The pyramid shape makes it a bit tricky to fit in; especially since they suggest it be above your sump or wherever it draws water from.
Very happy with it. Really is the greatest advancement in the fabledULM setup since the AWC using DOS pump system.
So far so...so good By Me on 8/22/2019Me would recommend this product to a friendI have had reef tanks off and on for 5+ years with various levels of success. I have been able to maintain and accurately test for NO3 and Phosphates but never felt like I had a grip on my Alk/Ca/Mg. In the past it was always a best guess and replenishment came via inconsistent water changes (to control the NO3/phosphates.
With my “dream” tank I decided to commit to testing and understanding more parameters as well as dosing. Unfortunately (most likely due to user error) testing with both Hannah Checkers and Red Sea test kits I always get different results and don’t know what to trust (especially with the calcium). I would test 4 times over 48 hours then setup and tweak my DOS pumps but would find my Ca shooting up rapidly only to compare it to the other test kit and find a different number. I would test 2 or 3 times with each test kit because I had no confidence in the numbers, the kits, or my methodology.
Enter the Neptune Trident. If this device lives up to the hype, coupled with great life support equipment (pumps, lights, etc), it will be the key to unlocking the SPS tank for the average aquarist.
Setup was incredibly easy (follow the instructions). It required a firmware update and it was up and running. I set it to 8 tests a day so I could get a great picture of my aquarium and once I’ve got my dosing dialed in I’ll roll it back to 4 times a day.
The drain and sample lines: are too short. 10’ would have been more ideal (you can always just loosely spool them). Not sure if 5’ was the maximum or just the number Apex chose to use so it’s hard to fault them here. I assumed the water lines were standard airline tubing; they are not. This means you can easily extend the drain line by feeding it into a wider diameter tubing (like ro/di tubing).
The actual unit is the same quality as other Neptune Apex equipment. Decent but not Kessil/Ecotech grade plastic... in signature grey. It is much smaller than I was expecting which was a great surprise. The shape of the unit is somewhat confusing. Typically something like this will be hidden and so making it a simple cube would have been more efficient. The artsy form factor just seems somewhat unnecessary.
It does make noise but it really isn’t bad. Especially since it’s only 4 times a day (for most installs). If you run AC pumps or power heads you won’t notice it.
The maintenance thing: Finding out there’s a $200 servicing fee required every year or so (or a $100 DIY kit) was kind of a shock and Neptune should have been more forthright with this information. I actually didn’t learn about it until mine was in the mail. It wouldn’t have changed anything for me, but might for others and BRS should probably be telling people when they call them. I think they thought this would be less of a big deal for people who drop thousands of dollars on their equipment but the forum backlash seems to tell a different story.
I’ve been waiting for this for a long time. I’m very happy with my purchase and really feel like this was the final piece in my quest for an ultra low maintenance SPS tank.
Set it and forget it By Dat on 7/9/2019Dat would recommend this product to a friendAll my comments is PERFECT. Btw, just like using a car needs tire and brake every year.
Any update on the release date?
Unfortunately we still do not have any update on the release. We are hoping for Black Friday or Christmas time!
How will these work with a calcium reactor?
Great question! There is no formal wizard at this time that allows for the control of a calcium reactor (CaRx) with the Trident.
It is Neptune Systems opinion that a CaRx should handle 90% of your calcification needs and the additional 10% or so, can be modulated through liquid dosing. A Trident paired with a DŌS can dynamically control that liquid additive for the delivering the most appropriate amount for the current rate of calcification.
With all that being said, there are certainly CaRx users that are using the Trident to control their CaRx. Visit the link below on the Neptune Systems Community Forum to see how and please let us know if you have any further questions. Happy Reefing!
Does the Trident work with the apexLE?
Thank you for reaching out to us. The Trident will work with the APEX EL.
Let us know if you have any further questions and take care!
I read about a requirement to send in the Trident to Neptune for annual maintenance. I didn't see anything like that in the instructions or on the Neptune website... Is it true my Trident will have to be sent annually for maintenance?
Neptune has said that there will be some program but there have not been any official announcements or details.
I have the Apex Classic, if I purchase the new Apex Base Unit, is that all I’ll need to add this to my system?
If you replace your old head unit with the new Apex Base Unit you will be able to run the Trident when it comes out.
Now that these are out, (and I'm sure someone there grabbed one ;-), can you give me the size measurements? I'm rearranging things under my tank, and want to figure out how much space to leave for it.
12" x 4 1/2" x 10" (L,W,H). Happy Reefing!
