I've had my 250 gal tank for a year now and have battled algea for about 7 months of that year. I've tried everything from weekly water changes to every day filter sock changes. I've purchased a uv steralizer and can't find the desire to use it. I have kessil 360 tuna blue lighting set at 40 percent intensity in a 3 ft deep tank. My nitrate level is between 0 and 5 And other levels are normal. Does anyone know if changing the light setting would help before I give up and just take the tank down?
