IME - some of the home floursecents work and some don't do very well for planted aquaria. What is marked on the end of the tube?
Also, I have found that a lot of those home use bulbs do not last very long. The color of the light shifts as they age. So, if its used, be wary of it. Especially if you see those dark stripes on the ends of the bulb when you fire it up.
I have used those $5 daylight tubes from HD with a lot success. But, I changed them at least every 6 months. I didn't see an advantage with the more expensive P&A bulbs.
