My 2x65 watt PC fixture gave up the ghost and I replaced it with a 2x54 HO T5 fixture on my standard 55 gallon. I plan on moving up to a 75 gallon in a month or so. The T5 lights are so much brighter than the PC's that I'd not have believed it without seeing it. My question is, is the T5 fixture enough for a 75 gallon to grow plants that I currently have - l. aromatica, riccia, l. cuba, tonina, riccia, etc or will I need to add another T5 bulb?
