So for the past month or two I have noticed some of my SPS's at the top of my tank bleaching and really had no idea as to why this was happening. Initially, I thought my lights were too high intensity so I turned them down to roughly 20% each. I was still showing signs of bleaching. I was going crazy trying to figure out what the deal was. I thought it could have been my alk or Ca, nope both were fine 9.0 and 450. Well last night I decided to go out, I finally came home about 2:30am only to notice my reef breeders unit on almost full blast. I went over the the unit and noticed the controller was reading zero for both blues and whites (like it is suppose to since I have it on a custom from dusk till dawn) I scroll through the settings and boom it goes off. I contacted Logan from reef breeders, he got back to me and is sending out a new controller. I thought I would share this little bit of info, thank god for late night boozing....
