Hello I have been keeping a 50 gal aquarium for some time using only t8 2x30 watt bulbs, I want to uprgrade in lighting and start growing plants like Rotala Macrandra, Althernanthera reinekii and other hight light plants. My tank has a depth of 24 inchs, and is 36 inchs long. I was thinking of using a T5HO 4x39 watt and only using 3 out of the 4 bulbs. Is this a good idea? What Brands do you recomend and have you had any succes with a particuler fixture. Thanks
