Greetings,
I have a biocube hqi, the one with the metal halide light. I have 2 little clowns, 2 peppermint shrimp, and an assortment of crabs and snails. I was running the light for 8 hours a day. The cleanup crew could not handle all the algae that grew. I noticed that there was barely any algae growing on the parts of the rocks that were shaded so I cut the light to less than 4 hours a day. The amout of algae has been reduced dramatically.
How long does the light have to be on? I would like to continue discouraging the algae growth, but I want to make sure I have the light on long enough to make everyone happy.
Thanks for the advice.
