I am looking for bulb ideas for dimming my lighting a bit. I have 2* 36” light fixtures across my 210G tank that I feel are a little too bright. The fish tend to become far less active when they are on and most of my bottom feeders go into hiding until they are off. I don’t have any live plants so I am not worried about that. I have noticed some Cichlid tanks in pet shops have almost a blue tint to the lighting. Is that something that might be an option for my tank?
