Hey Ned
I have a 24" 20 gallon tank with a 24 watt bulb that's on about 6 hours a day. There are no real plants in the tank so the light is only for seeing the fish.
About 2 weeks after I clean the tank a lot of brown algae appears on also everything.
Do you have any products that will kill off the brown algae and keep it away? Would a UV sterilizer kill off the brown algae?
