I am with doug here I have never seen this before
and Its hard to give any advice other than try to find where the nutriment came,dont feed,keep you hand off,do water change,diatom filter if you have, if you dont have put a magnum diatom filter
in the input bulkhead of you sump and clean it everyday,polyfilter,IMO UV is good only in conjonction whith a diatom filter because you have to get the algea out after you kill it other than that you will have a amonia peak and a big unbalance. wich you good luck
