One might say, well VHO creates a better bang for the buck and it's all I can afford. However, that's not true once you sit down and crunch the math. By the book, you need to replace VHO bulbs twice as often as MH, so this adds up over time. Therefore your cost eventually equals out and even becomes more expensive for VHO.
On top of that, MH puts out a much better quality of light than VHO. I myself have never owned MH to this point, but I'm so envious of the cool MH ripple effect that is impossible with any flourescent. :lol:
Fact of the matter, if you're serious about setting up a powerful and versatile reef for the long term, the only way to go is MH. No regrets with MH.
