how many watts of light, whether fluorescent or VHO would you need for a fish only 75 gallon tank if all you wish to add would be a calerpa bisma worm rock and be able to keep this rock alive? do you recommend VHO over fluorescent for this purpose? i'm not sure if a 48" 10,000 and a 48" 20,000 K bulb would do it. Right now i have 50/50 and a 10,000K bulb...80 watts total
