The bulbs are maybe a month old now.. You think I should move the fixture down a bit?? What would you expect the readings to be around?
Matt you can rent the Chicago Reefs Par meter for free..
Let your coral acclimate a little more and maybe in a month or so drop a inch or to would like to see 300-350 at your highest point if you can get there . How high are your lights?
