DDR DOS Dual Reservoir

This 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.

Listen 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.

Both the ddrs leak and interface cards failed to communicate with Alex after a few months.

As mentioned by the other reviewers, there is a serious flaw with these. I purchased mine on December 20th. Three weeks later the reservoir optical sensor starts indicating it is open (empty) even though it was actually full with 1900cc of Red Sea part A. On January 15, the DDR completely disappears from my Apex Fusion page. No where to be found, then several hours later it shows back up under the "new tiles" tab. I put it back in place and a little while later it disappears again! I go through this exercise four times in one afternoon. I asked Neptune for customer support and they said it was the connector to the DOS that was probably loose. NO its perfectly seated. I contact them again and they responded that they needed it shipped back to them. It's on its way to be evaluated. This is not worth $200 dollars. Its simply a nice looking acrylic container with lids and level sensors that obviously fail frequently. I would not buy again if I had the choice.

Don't buy this! Terrible product, even worse customer service. I'm very disappointed.

sensor failed,neptune said it got wet on top of unit,how can this not be water proof for a dosing container,cost 20 bucks to ship it their and 55 bucks for repair,took two weeks to get back.neptune needs to improve customer service.hopefully another controller company comes out with better service.

I have two of these. They look nice and have a small footprint but, I wish they where taller to hold more fluid. The big problem is one of the optical sensors fell off. After reading many reviews of Neptune's' less than stellar customer service I decided to just let it sit on the bottom. For $200.00 I expect more from a quality standpoint and shouldn't be reading so many reviews about their lack of customer service.

Neptune wanted cash to replace the sensor because of damage due to spillage. It's almost impossible to avoid all spills and just a little bit of anything seems to destroy this unit. Time for a re-engineer on this one!

sensor fell on 2 of these apex sells junk look at there reviews on all there add ons

Sensors keep failing. Also shipping at my expense to get it repaired to Neptune is ridiculous. Don't waste your money.

The board failed due to damage from liquid spilling on the top. It's almost impossible to keep a dosing container completely dry. Not useable in my setup.

It worked fabulously until one sensor broke off of its bracket within the container well within a year of purchase. Looking back, I wish I had just left it there sitting on the bottom. But instead, I jumped through all of the hoops required to send it back at my own expense and got it back in apx 2-3 wks. When I got it back and attempted to reinstall, the plug partly pulled off of the wire (there are no less than 8 TINY single wires within the wire which feed into equally tiny holes in the plug) which had to be reinserted before it would work. Got that done with surgical loops and a significant amount of effort. Once successfully reinstalled I noticed that the alk was now creeping up the wire on the side with the new sensor such that it continuously cakes up around where it exits the container and all around the lid. Alk crumbles now go everywhere each time I open the lid, including inside the container where I worry about it clogging up the pump. When I attempted to remove the unit to clean off said crumbles, the ENTIRE plug pulled away from the wire despite my greatest care. So now it's messy AND the sensor doesn't work. But I just don't think I'm up for dealing with Neptune again for repair. May just pull the sensor out of that side and use it as a vessel only, albeit a fancy one. It is a huge disappointment for something that was so expensive. I think they could do a lot to improve the design and make it very functional. I cannot recommend it in its present state, however.
