## Description

Elos OsmoController - Advanced Auto Top-off The OSMOCONTROLLER Digital uses a patent pending digital sensor with NO MOVING PARTS. To provide an adequate fail-safe the OSMOCONTROLLER Digital uses a small microprocessor in combination with a patent pending sensor to control the pump while also monitoring the top off of your system. The OSMOCONTROLLER Digital also has a manual top off button that can be used to use the system as a pump for occasional water changes and to fill a container with RO/DI water easily. The set up of the OSMOCONTROLLER Digital is very simple. It works with most sumps without the need for programming. The unique sensor design has a built in buffer for waves and small changes in the sump that will normally cause a top off system to unnecessarily top off, which will shorten the useable life of the top off pump. Ideal for smaller reef aquariums where a small modification of the water level MUST be avoided to keep the salinity constant.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Amazing customer service
  

*by D***I on Reviewed in the United States on January 16, 2015*

I've had one of these units that has worked for over 5 years, flawlessly. I had another one that did not perform so well, and when the old sensor seemed to crap out, ELOS sent me a new one, no questions asked. They didn't even ask me to return the old one. Then the new sensor was not working in either, so they asked me to send in the entire unit. I did, and a few weeks later the entire thing was replaced - new pump, unit, and sensor. Again, no questions asked and the thing is working great. ELOS customer support is amazing, and this is a cool little product.Only downsides?There is no tube in the kit for the water to pump into your tank with. This is reasonable because all tanks and ATO placements vary, so you'll need to get one that fits your situation. Still, it would be a nice gesture to have it in the box. Two - doesn't seem to have the best redundancy if the unit or sensor starts to malfunction, but there great customer service makes up for that :) I doubt these are able to fail in the on position, so flooding is not a concern of mine, but do your research on that before buying :)
