Lighting

Well I've decided my first step should be to build a nice stand for my aquarium. Actually the stand i'm building right now is going to hold two 75's and a sump, and I'm curious about what can I do as far as lighting. I'd really like to do everything right with this tank, so I think metal halide is the way to go. I really don't care for the prices of metal halide aquarium tops and I'd really like to have all of the lighting built directly into my stand. I still don't quite understand why metal halides need a ballast instead of being able to draw current directly from a US 120v system, unless they need a higher voltage. I'd like to try and achieve 5-10 wpg with this tank, landing somewhere in the middle (around 7.5) I think would probably be best? Can anyone recommend a good ballast/bulb combination that is cost effective and if not perhaps VHO is a better choice?

Thanks,
Ken

5 WPG with MH would allow you to keep anything you wanted. I have CoralVue MH lights and have had no problem with them. The guy I purchased mine from was selling 2- 250w MH retros with the bulb of your choice for $340 (includes shipping)

Why do you want a 400w light? Extreme overkill. What is your tank dimensions? That is not the correct bulb for your tank. It is a 4K. You would have a algae farm. You need a 10k, 14k, or 20k depending on how much blue hue you want in your tank. Also that ballast is entirely exposed. IMO asking for trouble around SW unless you have a really good place for it. You also need a reflector.

400w/75g = 5.something wpg. Which if I wanted to do high-light corals would enable me to do so. Also it will be a very custom stand and i'll have the ballasts mounted somewhere away from the tanks, probably below with the sump in a waterproof chamber with the rest of the electronics.

Does not work that way. The 5 WPG is a general rule. Very general. This is why I asked for your tank dimensions. Your tank is probably around 4' long? A MH will only cover a 2'x2' area. You will need 2 bulbs at minimum.

Here is an article I found that will explain everything you ever wanted to know about the mechanics of MH lighting and why you need a special ballast to power the bulb.

Also, I just put a 250W MH DIY setup together for a around $125 bucks. Here are some relatively inexpensive options:

i agree with what brian said..you need w mh bulbs. and 2 400watt bulbs on a 75 gal is a little overkill. i would go with 2 250watt.

I could ride to work on a pocket rocket too but that’s not really the “best option”. What’s next, saving money by buying your lr at the gravel pit?



Just kidding but really please buy supplies designed for aquarium use. There are shortcuts to cutting costs as Serpentman mentioned but not buying the right equipment can cost you more money in the long run and could be detrimental to your tank.

Hey that is a good idea...What kind of MPG does that thing get?
