mh light question

well i already have 4 65w coralife 2 blue 2 white

 

all i need is the mh right

 

thats great since you have the 65w pc. then all you need is the mh bulbs with ballasts. i would go electronic ballast since they fire anything. heres a site
Hamilton Technology Corporation
they also sell the hammertone reflector which is 99%
also needed is fans, you can pick that up at radio shack the higher the cfm the better

 

what does the bassalt do?

 

ballast fires the bulb. your pc's also have a ballast

 

what do the bulbs plug into

 

you can get Outer Orbit 150 watt Metal Halides for $129 from marinedepot.com inludes everything needed, picked up two of them for my 29 gallon, one was 10000k and the other 14000k, wanted to see what one looks better, the 10000k is a crisp white light while the 14000k is blueish, i'm going to order another 14000k bulb, I like the look better
heres a link to what they look like
