hello I have a 20g sps lps tank and I am looking for the most suitable lighting program and light height. The dimensions of my tank are 60x50x35 height 14" inches (35cm) I am waiting for your help for the most suitable program and density. I am sharing the image of the tank for an idea
My tank is only 14 months old and I only added SPS about 4 months ago. Overall the health of the tank is terrific right now. All the corals have vibrant colors with slow but consistent growth occurring.
I would say the XR15 is a powerful light for a small tank and you probably want to start off somewhere around 40% overall intensity via the schedule adjustment. Guage your corals response and slowly increase intensity as needed.
