U really don't need to run them bc there's no photosynthetic organisms, the bacteria will grow with or with out lights..but bc u are running the lights like I do during. The cycle, you will get algea growth.. what are ur readings? Amonia, nitate, trites? Ph, salinity? Did u use anything to kick off the cycle? After itsd running I use a pich of flake food once a day to give the bacteria something to use as energy.. also if your amonia isn't high, you can add a few snails to take care of the hair algea before it gets out of control, also if it isn't ready for any livestock(high levels still) use ur hands and pull it off and out of the tank b4 it spreads..make sure u have no sunlight from a window hitting the tank that will cause unwanted algea blooms... when the tank starts getting covered in brown film its ok and normal and will go away on its own twards the end of the cycle...
