I was wondering if for a 14gal bio-cube, if 72 watt MH would suffice for sps?

A 70 watt HQI will be enough to support SPS. The basic rule with MH/HQI is that each bulb will cover approximately (depending upon height), a 2*2 square. The depth of the light is what changes with upping the wattage. So a 70 watter may not do well at deeper than 12", while a 150 goes to about 18-20", and a 250 watt HQI goes to 24-36"...and these are all depending upon variables in light, spectrum, etc.
Does that help?

Hi Jon,
I haven't noticed you around for a while. Welcome back.

Yeah...been hiding. I thought i would revisit and make sure i kept up connections here on this site! I hope to be back in the hobby eventually! I do miss the tanks right now, though!

Duke1231, I agree that wattage is more then sufficient for supporting SPS Coral specimens. Howeve be careful as to the placement. I am noticing an area within my 28 gallon Nano cube HQI SPS Reef Aquarium with a 150 watt Metal Halide HQI Lighting System that I cannot place SPS Coral specimens past due to too much light being available at that point and stressing the SPS Coral specimen.
