Or you might split the difference and reduce the photo period to 8 hrs. and you should be adding one third phosphates to your ferts so if you were adding 10 teaspoons of KNO3 you would then mix in 3.33 teaspoons of KH2PO4 to you solution or how ever you might do it. I used to use a UV sterilizer but they are expensive and don't last a long time so I find it better to just find the problem and make the corrections and most of the time if you just make the proper adjustment and watch for a couple of weeks you'll get results.
My algae is under control to the point that I only have a very slight amount of dust that is not visible unless you look hard and the MagFloat takes it right off.
