I am running a custom program on the Prime 16HD. After I got through the “ugly” stages (in my case primarily diatoms), I haven’t had to deal with too much nuisance algae other than a little bubble algae and some GHA, which has cleared up with nutrient control. For cool, late night viewing with all other ambient lighting off, I’ve been running 2% UV/Violet/Royal from 9:30-10P and 1%. UV/Violet/Royal from 10:30P before shutting off. All my corals have been showing significant growth, but especially my euphyllia, kryptonite Caulastraea, and zoas (there are 4 different types in the tank now).What is your programming you have on the AI Prime currently?
Here are a couple recent shots of the tank for reference:
