Hello,
We installed a brand new Reef Breeders EXO ATO into the return chamber of a BioCube 29. Installed on the back clear glass. It turns on immediately regardless of placement relative to the water surface and never turns off. I then placed it in another clear vessel on a table and it worked normally and correctly. Placed it back in the biocube and then the same as before always runs. Shined a light down into the return chamber and it works correctly as long at the light is shining on it. Strange. This ATO is supposed to work in the dark , correct? IS this one just bad out of the box? Thoughts?
