Hey me and my roommate are trying to establish a 10g reef tank we just started to cycle. Right now we have 7lbs of liverock and then some other regular rock, we also have some live sand. Currently we have 2 15 watt fluorescent fixtures, one has a Coral Sun Actinic 420 bulb and the other a regular daylight. Remember its only a 10g tank, and if i am assuming correctly that wattages add, we have 3w/g. Will this be enough to get our live rock really cooking? How much lighting do you guys recommend that wouldnt break the bank?
