vho or not

[sod]

i have a 30 gal tank and right now i can get a brand new 24" xho extra high output power compact light for $131 but i think that my tank is small and i know i will be upgradeing to a bigger tank soon and my question is should i get the 36" 4 bulb powere compact for $195 so when i up grade it will cover more? i would also like to know what size tank is 36"long? oh by the way the power compact light is a phaser 4 by red sea pharm and it is on sale at www.petwhse.com it is on clearence for 30-40%off

Rule of thumb is 3-5 watts per gallon. I have a 110 long with 320 watts of VHO lighting. I have an abundance of zooanthids, colony anenomes, and corraline growing everywhere, rather rapidly. There are many ways to obtain good results, do some research, and know your budget and I'm sure things will go well.
