Most would suggest the tank to be up for a year before adding anything like this. It will be two to four weeks before the tank is even cycled and you can't even add a fish until the tank the cycled. Reef is recommend three to five watts per gallon for the light depending on what kind of corals you want in there. I would HIGHLY suggest going a little bigger for the tank size. At least a 30 gallon if that is all you can afford. Smaller tanks (as funny as it may sound) usually requires a more experienced person. Now if you do a 10 gallon you probably don't have to wait a year lol but still a good amount of time maybe 6 months.
