6' tank with 3 of the taotronics ebay lights...they grow coral great but not the nicest setup.. works for me, but along the top there are areas of shadow.. they come with a hanging kit I never put up so the lights are just sitting on the glass.. penitrates 30" down well great coral growth, even sps.. check out my build thread for pics

How many would you need for a 48 in 75 gal. I to am in need of new lighting. I have a large cyno problem I. think its due to a color change in mh bulbs since it is not growing in areas where the light is not shining.
