MH over a 20 gallon...

[canuckzilla]

I've got a twenty and have eventually settled on a coralife aqualight pro which has made my tank very happy. It's provided me great versatility in how I can stock the tank and in turn the reef has been thriving...not just surviving.

Built into the light:
One 150 watt 10,000K double-ended HQI metal halide lamp
Two 65 watt True Actinic 03 Blue square-pin compact fluorescent lamps
Two 1 watt Lunar Blue-Moon-Glow 470nm LED lamps

No doubt, it was pricey but for me it was worth saving up for it given what I wanted for both looks and effectiveness.
