Using 2 Rapid onyx led's manually set at 100% from 11 am to 6 pm, and 1/4% all other times, other than moonlights from 8pm to 8am, there was no algae, but in the last section of tank run with 1 current orbit 24 inch, lot's of algae. Replaced the Orbit with the Rapid Corona and will see if the algae decreases.
