ok i'm setting up a nano, but want to add metal halide, since it's a 10 gallon i was thinking a 70 watt, does anyone have a recommendation, as to what to go with? where can i get the 70? where's a good place to shop?

At 10 gallons you shouldn't need more than around 50W of light.
Also, unless you provide good ventilation the MH may substantialy heat up your 10 gallons of water.

Good luck.

Ask and ye shall receive:
70 Watt Ushio 10K Double-ended HQI

It also has ballast information lower on the page so you can DIY your own halide if you like (you'll have to retrofit any halide you buy anyway for a 10g I imagine).
Make sure to buy plenty of fans...
Mmmm... do I smell something cooking?

Yup! Better have the MH high enough off the water and lots of fans as stated! Don't want to see a bubbling hot spring in your 10 gallon nano!

Holy Evaporation Batman!! you will need plenty of top off water also.
