I have a nanocube 28 hood with a 150-watt MH in it that you can try to balance over your tank if you want. Sorry, that's the best I have. I'm using my 250-watt MH over my frag tank, otherwise I would have that to let you borrow.
If you want to try the nanocube 28 hood, give me a chance to fire it up first to make sure it works. It's been in storage for awhile.
