Change can be a difficult thing and over the years I have certainly had my moments of resisting it…this is true for life in general and, specifically, the reef aquarium hobby. Hey, I am still holding on to my metal halides ? Nonetheless, I do believe change is a good thing when it makes sense. I have been tending to reef tanks for 25+ years and for most of that time I have been using a Neptune apex controller to monitor my tank and control the equipment. But change is in the air.
