Hey Geoff,
check out this thread on craigslist, its fro a 4x54w Teklight t-5 setup.... a really good deal and would be prefect for your tank.

I'm looking to get my hands on a couple of things.
I'm looking for:
a used MJ900 or MJ1200
a small Kenya tree frag
I had a fairly large Kenya tree which the little lady loved, but it died a few months back. I need to keep in good standing w/ her if I'm to make that next tank upgrade(wife)
