This is a great little device. As you can see in my photo it's so small that the cord for my power head partially covered the device so I had to circle it to make it visible. I've run it in a 36 gallon arc for a month now and have no complaints. The salinity in my tank is constant at 1.026 for every measurement. I was hesitant to spend money on something that could be done with manually resetting fresh RODI daily, but I forgot some days and I love that my pets can now depend on a constant salinity level for their home.
