Two-part liquid storage automation made simple.

  • High Capacity to Size Ratio = each side stores two liters (2L) of fluid
  • Connects directly to your Apex DOS
  • Optical sensors inform your APEX in real-time when dosing levels inside the DDR reservoirs are low
  •  Cast-acrylic constructio
  • Low-profile with Low Center of Gravity = stays put and doesn't tip over easily
  • Easy to refill
  • Push-fit tubing connections
  • Use for 2-part (Alk/Calc) additives as well as other applications

 

Style Meets Function, Deceiving Capacity and No-Tip Design

The DDR has great style and will stand out in anyones equipment room. But it’s not just about style. It may not look like it, but each side of the reservoir holds an ample two liters (2000 mL) of fluid. For most saltwater aquariums that are dosing Calcium and Alkalinity to their aquariums, this amount is more than enough to last at least two weeks. If you were dosing other additives it might last months before needing a refill.

Speaking of refills, the DDR has easy lift off lids that make refilling it super easy.

The DDR was also designed to have a low center of gravity. This means, unlike other reservoirs on the market, it is very difficult to inadvertently tip over and ruin your day.

Connect Directly to DOS Pump

The DDR is the only dosing container on the market that connects electrically to your DŌS and uses optical sensors that alert you when your fluid has approximately 20% remaining.

Optical Sensor Alerts

One simple connection links the DDR to the DŌS. No worries about fooling around with loose wires, float switches, etc. Just plug it in and it will show up in your Apex Fusion Dashboard.

Very quite motor

Love this pump. Works like a champ.

Absolutely amazing customer service!

I ordered this unintentionally and wrote in to Two Tides for help. Tyler was back in touch within probably an hour. I was in a place where I couldn’t respond so he reached out two more times until we were able to connect. Instead of just letting it go he made an amazing effort to make sure I got the fuzzy socks too. Every review you read about Tyler is true. I am definitely buying all my stuff from them going forward, I wish they had a bigger assortment of products but this place is all about customer service. I wish the other online marine stores were this good.

Best Bang for your Buck!

I’ve used these lights on my Nano Reef tanks for well over a year now so I decided to roll the dice and run four over my newly purchased Prostar 200 Aqaurium even though they aren’t intended for larger tanks. Paired with the 18 inch flex mounts these lights offer a clean high end look for under $1K. The best part is they can provide enough even solid PAR spread to run a mixed Reef tank if you plan accordingly. The app is easy to use when you get the hang of it and their website has plenty of presets that you can download to make set up a breeze. If your looking for a high end reef capable light without the high end cost and bulky appearance then this is a good choice.

Thank you Tyler for getting these to me quickly!
