One of our 3 fish stores we deal with told us to turn down our white light % and use the 23k program for our reef tank. Would like to get general thoughts. For reference we use 2 Red Sea Reef LED 50’s and had them on the 23k program with blue at 100% and white at 50% for mixed coral. Fish store suggested we adjust white down to 10% from original 50%. Tank is the Red Sea Reefer 350. Thanks.
