Some people have differing opinons on lighting during the cycle. Personally, I use a short lighting period (5 hours/day or so) to ensure that the calcareous algae and any hitchhiker corals will survive. Some people don't use light because they think it will cause an undesirable algae outbreak. 5hr/day right now would be enough. Once you have the cycle completed you can increase your photoperiod to 8-10 hours/day depending on your lights, inhabitants, and personal viewing preferences. If you have not yet purchased a variety of test kits, now would be the time to do so. It is worth the little extra money to get a quality kit like seachem, salifert, or LaMotte. You will need at the minimum ammonia, nitrite, and nitrate. Test these every other day or every few days. You will get readings on all of these during the cycle. When all 3 hit 0, the cycle is complete and you can add a clean up crew. This may take anywhere between 2 weeks to a month or more. Other test kits you should have before stocking your tank should be pH, alkalinity, and calcium. You need to ensure you have a stable pH and proper Ca to Alk ratio before stocking your tank with fish or corals. HTH
