5000 would be much better than 10,000 for a planted tank.  10,000 is
going to be very blue.

I run a mix of 5000 and 6700K bulbs in my aquarium.  I don't use metal
halides though, just CF.  The best CF bulbs that I've used are the 92
CRI 5000K 55w bulbs from ahsupply.com.  They work well on tanks that
are a multiple of 24" wide.

I have the parts on order to switch my 60 gallon planted tank from 6
T8 36W bulbs to 2 96W compact flourescent bulbs.  If anyone is
interested in some high quality ballasts for T8 bulbs let me know.
The bulbs that I have are way past their prime (although I think I
have two high-CRI 36" bulbs as spares somewhere), but the ballasts are
in good shape.  They are about a year old, I bought them from Bulbman
down near the stadiums.
