Uv to reduce green water
Hello, 20 gallon tank, tall hex, lots of Anubias, java moss, Marimo. 78 degrees , 1 dwarf gourami, 5 platies. Green water on and off. Want it gone. Do I need a uv sterilizing filter like the killing machine? Or could I just run a Uv stick on light bar from eBay / amazon? I don’t mess around with the algaesides , dangerous stuff! Tank is cycled , good readings, just having some issues with algae blooms . Cheers!!
