be careful with how much light you have over a planted aquarium. you need to ballance the following three things:

1. light
2. nitrate
3. CO2

if you increase the light but aren't dosing nitrate and carbon you'll have lots of algae. I'd say don't bother lighting it with MH unless you're willing to get into CO2 and nitrate dosing.
