I have a Maxspect L165 I use on one of my refugiums. I use 100% red, 30% green and 15 % blue which I read is a good setting for Chaeto. On my other tank I use a Nicrew Hyper Reef 30 and I keep it on high white whch I prefer. What setting are you using your Maxspect Jump at on Macro if you are? I don't know what setting to use on the Maxspect to get it to look white and there are no pre programmed settings for algae. I read blue actually can stifle Macro Algae.
