Okay, I tried to search this and came up with so many different searches that I am going to post this ?
I am looking into retro MH kits( 6ft long).
How much should this cost and what do I need to do this?
I have no electrical skills.

I plan on building a canopy for my new tank.
AGA 125 72L x 18H x 18D

You can get retro kits that are more plug and play than an electrical installation... meaning the ballasts are already housed in a enclosure and wired up. The cord that comes out of the ballast box plugs into another cord coming from the light socket or pendant enclosure. Do a search for PFO Ballasts...
Cost will depend on the type of MH and the wattage you choose.
What corals do you plan to keep??

I just purchased a retro MH setup with 4/400 MHs with 14,000 bulbs and it ran me right at $400.00. That was with reflectors, ballasts, bulbs. I plan on building my own hods as you are.

Reefnut, I am going to keep Sps, Mush, clams, lps, and softies. I will only have a few sps corals in the tank.
The cheapest that I have found is around 700.00. This is 3 mh 175 and VHO kit.

Do a search for cooltouchlighting. They make a 72" triple 175w MH / Dual 160w VHO retrofit kit - base price is $580.00. or they make a hanging pendant type canopy for 685.00. Both prices include the VHO bulbs but the MH bulbs are extra.

Thank you for the reply again Reefnut.
I have another question?
How many ballast do I need to run 3 mh bulbs?
There are so many different kinds of ballasts that I am getting confused.
single probe
dual probe
single pulse
dual pulse
electronic
magnetic

One ballast per-bulb... so you will need 3 ballasts. When they say "dual probe" or "dual pulse" that just means there are two ballasts in the same box.
There are three types of ballasts... Probe Start Magnetic, Pulse Start Magnetic & Electronic. When using Probe Start Ballasts you need to run a Probe Start Bulb... and when using a Pulse Start Ballast you need to run a Pulse Start Bulb... Electronic Ballasts will run both.

probe start ballast...magnetic ballast without internal ignitor. designed to run american style bulbs (bulbs that have ignitors built it). Coralvue,reflux,XM are examples of probe style bulbs. probe start ballast may not fire german style bulbs properly or at all (or by chance work fine).
pulse start...magnetic ballast with internal ignitor. designed to run german style bulbs (bulbs without built in ignitors). Most Ushio except 250 watt, Aqua Bushke, Radium are examples. These will fire any type of single ended bulb but may prematurely wear out or alter the coloration of pulse start bulbs. Sunlight supply's blue wave and special order PFO are the only commonly available aquarium pulse start ballast in america.
Magnetic ballast: see above. Most every bulb is designed to work with one or the other. they are ANSI coded. example: "M57" is the ANSI code for 175 watt probe start ballast and "M137" is the ANSI code for 175 watt pulse start. If you buy a probe start ballast bulbs designated with M57 were designed with that code of ballast in mind. If you buy a M137 bulb it may work fine but it might not and vise versa.
electronic: will work properly with either kind of bulb. some people not convinced of their reliability compared to tried and true magnetic since many earlier ones had reliability problems. bugs are probably ironed out by now.
single=fires one bulb. dual= two ballast in one housing for firing two bulbs. usually one switch and power cord so both operate together.
I went with sunlight supply blue wave 175 watt dual pulse start ballast because the bulbs I was most interested in using were german style and I could still fire american style if I wanted to use those. the only reason I went with sunlight supply over PFO is because pulse start is special order. I used sunlight supply reef optix 2 reflectors which are prewired with quick disconnect cords that plug right into the blue wave ballast. I paid $195 shipped for the ballast. $120 shipped for both reflectors and $75 each locally for the Aqualine 13K bulbs. so $470 total. Could have and almost went with Coralvue electronic ($170 per kit X2) which is cheaper but I had more confidence in sunlight supply and the bulbs I chose. I use two bulbs but the standard for a 6ft tank is 3 bulbs. I think mine is fine with two because I dont have any center bracing to block the light.
