Recently set up a 55 gallon, planted, community tank. I was given a few java ferns, some java moss, and bought two amazon swords and something I forget the name of. I let it cycle for days with just live gravel and sand before adding plants and two weeks before adding fish. I currently have 10 Guppies, 3 Sunburst Platies, 2 Dalmatian Mollies, and some sort of serpentine Loach that came with the plants I was given. My swords are starting to turn yellow and some leaves have see-through patches starting. I am using the bulb that came with the tank. I know I've read about Watts per Gallon but does it matter what kind of florescent bulb I get?
