These are the BRS recommended spectra for the Prime 16HD. I have the Innovative Marine 15 AIO desktop aquarium. According to the BRS YouTube video, I should be in between 25% (which is what they recommend for a 12” cube for LPS) and 70% (which is what they recommend for an 18” cube for LPS). That would be about 48% of the 100% setting. Is it just me or do these numbers seem really high?
