Wow, I had a setup extremely similar that I setup in Jan 2007. 55 gal.,emperor 400, and a twin bulb shop light. I really regret not spending more though because plant growth is very slow and everything is covered in algae. Now I replaced the filter with a filstar xp3 and want to replace the lighting and add diy pressurized co2. Think about it, eventually you will pay. So I would suggest to get better quality stuff. On the other hand though, the fish are doing extremely well.
