Flawed Design By Michael on 1/21/2020
Michael wouldn't recommend this product to a friendThese reservoirs are beautiful, and are a perfect size for many purposes. They have gradations ti show fluid level and built-in optical sensors that trip at about 25% remaining capacity.
Unfortunately, the electronics packaging and design is atrocious. There is a bare circuit board right below the top of the unit (there is no conformal coating or any effort to seal the area), and a unsealed cable routed across the lid.To be clear, there are industry standard ways of making this type of design work (as mentioned, a conformal coating and ingress protection of the electronics area would be a start), but Neptune hasn't used any of them.
IF YOU OVERFILL THE RESERVOIR ONCE, THE UNIT WILL NEED REPAIR. Seriously- it's that bad. It isn't *if* the unit is going to fail, but when. A completely unprotected circuit board is mounted inches away from a reservoir intended for corrosive substances. Failure is guaranteed.
When mine failed, it also managed to take all of my alarms offline due to a Neptune programming bug, which required support to troubleshoot and address.
I am a big fan of Neptune products, but this one is pathetic. -
Bad design from Neptune system By Abbas on 1/7/2020
Abbas wouldn't recommend this product to a friendI got this two years ago. after few months one of sensor stop working and in few month later 2nd sensor stop working. Sent for repair Neptune systems charged me 50$+ shipping and told the board got wet. After repair it worked for 3 months or so then both sensor died again one by one. this time I was very careful that board does not get wet. So it is just bad quality product. Anyway the graphic still was working although sensors were broken. I could use it as a reminder for changing chemicals. Recently, I bought a new APEX controller. DDR unit never was recognized by the new APEX controller. Now, I have a 200$ container for my Ca and Alkalinity solution. BRS should stop selling this product until they resolve design issue. -
I Like It By Bradley on 12/5/2019
Bradley would recommend this product to a friendI really like this thing. I'v only had mine for about 3 weeks but it is working great. Looks very nice under my stand. Im giving this 4 stars because I know the sensors will go out at some point because these sensors are trash. I have a 8 month old ATK that I already had to replace one sensor so I know its only a matter of time. Other then that I really like it. If you buy anything Neptune that uses these sensors you will be replacing them for sure so just beware of that. -
Dud By Mark on 10/4/2019
Mark wouldn't recommend this product to a friendUnder a year old, could send back but onky worth it if the problem was fixed which I doubt will happen. Band aids don't justify having a dosing system down for a week or more. -
Sensors fail By VegetaD on 9/11/2019
VegetaD wouldn't recommend this product to a friendIt will be one year in October that I bought 2 of these and one had the sensor die 6 months ago and the other this past week. Save yourself the trouble and use regular containers and DIY sensors. $400 for less that 1 yr? -
Waste of money By Mark on 9/7/2019
Mark wouldn't recommend this product to a friendSimply put, all of the other reviews are right. This should have never made it to market. Shame on the manufacture for continuing with this. -
Same story... works few weeks.... By Jeffrey on 8/14/2019
Jeffrey wouldn't recommend this product to a friendWorked for several weeks, then switch would suddenly show closed... open... closed etc even when full. The a short while later disappeared altogether from fusion. Now nothing more than an expensive acrylic container. Neptune makes some great products. This DDR isn’t one of them. -
Do Not Waste Your Money By Nueok on 8/12/2019
Nueok wouldn't recommend this product to a friendDont buy this. I never got to see the sensor work once. I only dose 5ml to my tank daily so to empty it takes a while. But when the actual water level went below the sensor, only one side triggered the alram. I didnt bother replacing the unit as Neptunes warranty is you pay and pack to them for warranty service. I didnt feel like emptying the container to send everything back as the Fusion Display shows levels anyways. But now the whole thing does not even show up in the dashboard. Contacting Netpune, its the same thing, fill this form out and ship it to us. -
Junk - not waterproof By Mark on 7/8/2019
Mark wouldn't recommend this product to a friendThis is my second unit. Not sure why Neptune continues to design modules that are not waterproof. Now unit even showing in dashboard. Will just use it as a very expensive container. Shame on Neptune. -
Not worth the money and very bad customer serves!!!!! By Wayne on 3/28/2019
Wayne wouldn't recommend this product to a friendThis was the biggest waste of money ever. The first one lasted a week and a half. Traded it out and the 2nd lasted the same. I had to send it to Neptune. they said you can not get the top wet it gets into the board that works the sensors. Why would you design something that holds fluids not to get wet? THey said they would fix it one time and any more I would have to pay to get it fixed. Why should I have to pay to fix something that Neptune poorly designed? To me that is very wrong of them. I have had none stop issue with just about everything I have got with my Apex and I have a lot of addons. I am in the process of switching to GHL something I wish I would had done for the get go. The customer service is the worst I have ever dealt with as well. Im telling you stay away from apex. -
Definitely a stinker... By Ant on 2/7/2019
Ant wouldn't recommend this product to a friendListen to what people are saying about this container. The container itself is nice, but the sensors are absolute garbage. Both my units had sensors fry and I'm talking FRY like short out and leave burn marks on the plastic nut. The whole experience has me second guessing ALL Neptune gear that uses optical sensors. -
Poor construction quality By Heath on 2/4/2019
Heath wouldn't recommend this product to a friendBoth the ddrs leak and interface cards failed to communicate with Alex after a few months.
Can this be used without Dos? Plugged right into a aquabus
Question posted on Apr 12, 2016 7:36:00 PM
Great question!
The DDR requires a 6 pin connector which currently is only on the DOS itself and not on the 1Link module or other modules. Feel free to let us know if you have any further questions!

Does this connect with 2- BOB or 1-Aquabus cable?
Question posted on May 22, 2015 1:30:00 PM
Great Question,
This unit will connect directly to one of the accessory ports on the DOS. This leaves one extra accessory port for future monitors and the Aquabus cables free for daisy chaining.
