I currently have a Current USA Orbit Marine LED Light (18-24 in) on my 24 g nano. Looking to do mushrooms and zoas. I am running the light for 8 hours of sunlight a day w/a hour of dawn/dusk before. I do not want to upgrade this light because I plan on upgrading the tank within the year. The tank has been up and running for several months now and houses 2 clowns and a peppermint shrimp along with crab/snails. I've read several different things on what the settings of the lights need to be at to include duration and red/blue coloration with the LEDs. I'm looking on for advice of what settings have worked best for others out there to grow their corals. Thanks in advance!
