The DOS has around a 20" head height, this means that you would need to place the pump either a little higher or lower in the line from the storage to the tank. It can work well however. Feel free to let us know if you have any further questions!

Have a great day!
This works great with the Apex controller gold! Feel free to let us know if you have any further questions!
The #1 reason people purchase a dosing system for their aquariums is for consistent and easy dosing of 2-part solutions (calcium and alkalinity) to their reef tanks. The most common method for doing this today is to use standalone dosing pumps and run them on a timer using seconds or minutes to determine how much to dose. This is not only confusing, but also prone to inaccuracy. Everyone knows that when measuring a fluid it is done by volume, not time. Every dosing calculators out there uses volume. So, with the DOS (and the Apex Fusion interface) you simply enter the amount you want of each part of the additives (one on each pump) and what hours of the day you want it delivered. The DOS then sets up all the dosing intervals within that time period. When that time interval is finished, the exact volume you set has been delivered. It even automatically chooses the slowest speed necessary for the pump so that it minimizes noise.
- Automated water changes - Water changes with the DOS are super easy. All you do is place your empty vessel and your fresh stock of saltwater under your stand. Then, with the Apex Fusion wizard just tell it an amount of water you want to change over what length of time and the hours of the day you want it to happen and it figures it all out for you. It will perform an automatic, continuous water change for you. It gets better. If you have our dual optical water sensing accessory Apex Fusion will send you an email or text message letting you know it is time to change out the jugs. Less time pumping, siphoning, and sloshing water and more time enjoying a great aquarium.
- Dosing micro amounts - If you need to dose tiny amounts of a particular solution, element or other fluid (like vodka dosing or Zeovit systems), the DOS is the perfect solution due to its precision controlled stepper motor. This ability to control pump movement in such a refined manner means that you can dose all the way down to 0.1ml at a time!
- Large diameter tubing - Larger size tubing means that your pump does not have to work nearly as hard – or stay on for longer cycles. The most popular dosing pumps on the market use tube fittings with the tiny diameter of 1.67mm. The DOS uses much larger tubing and fittings. In fact, at 3.33mm in diameter, the pump on the DOS can handle 4x the flow of the most common pump style on the market. This means that your pump (and motor) will run 1/4 the time to pump the same amount of fluid. Less run time means long pump life.
- Headache free interface - Programmability using Apex Fusion makes dosing a breeze.
- Quick and easy tubing changes - No matter the pump, your tubeset will eventually go bad. Changing out the peristaltic pump tubing on the DOS is a snap. Literally! All you need to do to change out the pump tubing is squeeze the pump head and remove. Then take out the tubing, replace with a new one, and snap it back on. No screws, no impossible snap on covers and no fussy loose rollers to mess with. And, because you are not changing out an entire pump head, your costs are lower as well!
- Adaptability - The DOS has an accessory port that will enable it to be connected to the DDR – Dual DOS Reservoir.
- Super silent operation - The Neptune Systems engineering team has taken extensive steps both in how the pump operates as well as the enclosure design to ensure that the DOS system is one of the quietest dosing systems on the market for the fluid volumes it delivers

Garbage. Skip it By Jennifer on 6/1/2017Jennifer wouldn't recommend this product to a friendHorrible pump. First pump was broken, new out of the box. Apex wanted a hefty sum to fix it and blamed me for the issues.
Second pump broke 6 months later. Wheels stopped turning. Purchased new wheels as it says they need to be replaced every 6 months or so many turns/hours. Still would not work with new wheels.
I wasn't willing to send the broken doser to Apex again, as they proved to me, the customer is always at fault, even with junk for equipement.
I went to a BMT01 doser and haven't had any issues with it.
Skip the Apex Dos.
Awesome, simply awesome By Casey on 1/3/2017Casey would recommend this product to a friendThis dosing pump is amazing. Super simple setup and you can dose literally a drop of whatever you are dosing. It's pricey but honestly, if you've already spent the money for the APEX, you owe it to yourself to get this. 10/10 would buy again.
Works great so far. Its only been a few weeks By steven on 5/23/2016steven would recommend this product to a friendI purchased for automatic water changes on my 300g. Right now im changing 6 gallons per day. so far it has worked flawlessly. It was very easy to setup using fusion. 1 thing to watch out for. If you select remove water during setup the pump will spin backwards.
For dosing this pump is fairly quiet, but when you are doing large water changes like i am the pump runs in high speed and it is noisy.
Noisy By David on 4/27/2016David wouldn't recommend this product to a friendOnly 5 weeks old and it started making a clicking and humming noise loud enough to annoy anyone watching TV in the same room, and the pump is inside the cabinet! I emailed support, sent pictures as requested, swapped the left and right heads for them. The answer they came back with was this: "It's highly likely more plastic pump heads will result in the same sounds. The plastic flexes and makes these sounds." That's a quote! I told them it didn't start out this loud. I know everyone says the service is great. My service experience was disappointing.
Awesome By ALEX on 4/11/2016ALEX would recommend this product to a friendThis doser does exactly what it should. Precise and accurate dosing is very important to the reef tank. This doser takes the guess work out and with a few simple steps it's ready to go.
Well designed and easy set-up By Kane on 3/31/2016Kane would recommend this product to a friendDOS was easy to install and set-up. Calibration is a few simple steps. Using it for 2-part addition. Only problem I had was not enough tubing so had to order more to install.
Great for 2 part and water changes! By craig on 3/23/2016craig would recommend this product to a friendMakes life very simple for 2 part and water changes (using 2 on the system)... the latter being my favorite benefit.
Great Doser By Mark on 3/6/2016Mark would recommend this product to a friendI love this Doser. I use it to dose 2 part. It was was easy to set up and is very quiet. Highly recommend. I set it up in Apex to dose Alk at night and Calcium during the day. Works like a charm and keeps my PH up at night. I also got the DDR to go with the DOS and now i know exactly how much 2 part i have left and Apex will notify me when the Alk or Calcium mixes get low.
If you have an Apex and are looking for a doser...this is it. By BTibb on 3/6/2016BTibb would recommend this product to a friendWith all the options, abilities, BRS customer support, and Neptune support...no brainer even with cost. Picked up one for 2-Part dosing, will be adding secoknd for AWC.
Great Time Saver By KerryF on 3/3/2016KerryF would recommend this product to a friendI have two of these, one for dosing and one foot AWC. Makes reefing a lot less work!
WOW!!!! Why did I wait so long By charles on 3/2/2016charles would recommend this product to a friendI first must admit that it took me a little time to get this product working. I could only get one pump to work and not the other. I will say that after a couple e-mails with Neptune and Bulk Reef Supply who were both great and provided excellent service helped me solve my problem and now all is great. I've heard others complain about the noise but to me really not that loud and my tank is in my bedroom...It's great having my two part dosed through out the day I run Cal. during the day time and Alk. at night. and my pH stays above 8.15....Don't wait it is worth the investment.
Neptune Apex DOS By Nate on 2/18/2016Nate would recommend this product to a friendSo far i have had mine for 3 days now and running. First i will say wow! this is my first dosing pump and im so glad that I bought it. I took my time with it to route everything they way i wanted it. But set up is easy through fusion. Make sure your apex is updated though. So with in the 2 days I have had it running and tested I have had almost no swings. DKH was 9.75 and today it was 9.6. that is awesome. my Cal has went up 5 ppm in 2 days. (420 to 425). I dont think its noisy either, I really have to listen for it. All in all it is another great product by Neptune.
