I look all over online and i cannot find 30" T5 replacement bulbs. Places that sell the fixture don't seem to have the bulbs either. I'm guessing that if I do find the bulb it will be overpriced. I wanted to get a 30" 4x24w for my 20 long. Maybe ill just go with the 24" version.
It is really odd that they would sell the fixture but no replacement bulbs. The 24" version has the same output as the 30". so i guess ill just have to go with that. It won't fit the tank perfectly though.
