Hi Lilben,
Ok well I am not an expert on UV sterilizers but I will try to help you out here. From my understanding UV sterilizers do not eliminate - cyanobacteria (blue green algae), diatoms (brown algae), dinoflagellates (brown slime algae) or chlorophyta (green/hair algae) and that appears (to me) to be cyanobacteria. What is your tank setup, fish, how often do you feed, and how long do you leave lights on?

Sorry meant to say that they do not prevent or eliminate those types of algae.

Ok I would recommend going to aqadvisor.com and double check but I think you are overstocked, which would lead to higher bioload. I would recommend upping your partial water changes/vacuuming substrate and if you aren't doing so already I would reduce lighting to 6 hours a day or try a black out for a couple of days and I would also recommend reducing the amount of food given.
