I have been having extreme white cloudiness in my 12 g nano cube. It is fully cycled but there is about 5 inches of visibility for the past 4 weeks. I have bought an extra HOB filter today and am running it. Am I crazy? Will this help the bacteria bloom or whatever it is? Nothing else seems to work. I have thus far taken pro advice and not used any chemicals. Kind of frustrated because the tank looks so heinous. It is heavily planted with 4w/g of light, but algae is more or less under control at this point.
