Hello ! This is my first message in NanoReef.com I live in Brasil and here we don't have PCs 10000K. I have a nano reef with 26G - real volume. I have Soft corals, Hard corals and few weeks ago I started with SPSs. I am using 4 PCs 25W each and an actinic 20W. These lamps don`t have 10.000K My first question is : Which kind of lamp can I use with 10000K (except MH) ? Is this parameter (Temperature K) the unique responsible for the great quality of corals colors ? Tks !
