Hello All. I've been out of the Reef game for the last 10 yrs. I decided to jump back in because my life is just not hectic enough lol. It seems that everything I thought i knew about reef keeping has changed. A few questions. I am setting up a Cad Lights AIO 8 gallon. I have about a 1.5 inch sand bed using live sand. I purchased 6lbs of live rock from my LSF that was in water circulating through their system. Am I going to go through the same cycle that I did in the past? Second, looking to update the old stock light. Keeping with a budget, I am looking at a NICREW 50 Watt light. The tank is 12*12*13, is this too much , not enough or just garbage. Appreciate the help.
