Thanks for your help, and yeah I was thinking of switching to like a 14k bulb or 15k bulb, is there one you would reccommend? And if I do this should I also switch the actinics, right now they are in the form of PCs.  My flow is really high, parameters are stable, only thing is I dont have any form of filtration besides the live rock.  I have never had the need to get a skimmer or anything.  Is this part of the problem?
