I'm all for it. Afterall, it was one of my suggestions in your previous thread about what to do with the new 30G tanks you aquired.
What's the dimensions of it? Is it a standard 29G tank that's 30" long? If so, you will run into some headaches finding a light fixture. The 30" is sort of an odd ball as there's no fixture that will give you 100% light coverage, unless you go with a double lamp fixture. The singles are usually only 21" long and I've seen some (Coralife) that has the lamp offset to one side.
If your wanting to make your own fixture, Coralife has a 13" bulb. You can use a dual ballast and operate two inline for 26" of light over 30".
