Q: What can I use to add more light to my tank (light bar). Looking for a more budget light bar to add to the back of my regular 55-gallon aquarium. I have 2 K7 mini noopsyche lights and the front of my tank gets decent light not my back for whatever reason. Would a 4-foot or 3-foot light bar work? If so what are some good budget brands that'll get me extra par back there. Thanks!
