We keep our acans/micros growing under ATI Blue Plus and Reef Brite blue LED’s, nutrition is provided by Polyplab Reef Roids and/or LRS frozen foods. Acans/micros thrive in nutrient rich environments with detectable PO4, NO3, and a DKH of 8(many corals will respond poorly to high DKH, please take that into consideration). It is our experience that most acans/micros do best in low light(less than 75 PAR). Acans can and often will change colors under different lighting. WYSIWYG
