I have a 50 gallon acrylic with 9 black skirt tetras and no live plants and I'm having an algae issue. The fake pirate's ship I have in there was from an older tank I had setup prior to this one. There is a slimy layer of green algae on both pieces but that's not the puzzling part.... when I wake up in the morning and turn my light on the water is green and murky, but when I turn the light off at night the water is crystal clear! I dont understand, I thought algae thrives on light? Shouldn't it be green water at the end of the day? I failed to mention my tank is not quite cycled yet, but it's close. Any tips on getting rid of this crud? Does hydrogen peroxide really work/harm fish? Any help would be greatly appreciated.
