Im looking for advice. I have a 20 gallon tall reef tank with a 150 watt metal halide (7hrs a day) and 30 watts of t5 actinic lighting(12hrs a day). my current corals are blue acropora, green star polyps both are frags 3'' to 4'' and a colony of orange and green zoanthids.some scinaia complanata (red macro algae) growing. The zoos and acropora are new. Any advice on if its needed or good compact led light sugestions would be great.
