i am going to buy a 4 x 55 watt pc for my 29 gal tank, it has two ballasts so normally it would be a 10000k/acitinic mix on each ballast. But i want to be able to have just the blue light on the tank if i want...will it effect the tank if i just put the acitinic bulbs together and the 10000k together? and would you put the blue in the back or the white in the back? any help would be appreciated THanks!
