i just bought a new light fixture for my tank it has the new t5 style lights. the bulbs were pre mounted and has 2 actinic and 2 15k bulbs theyre mounted 2 actinic in a row and the 2 15k after. should i place an actinic bulb between the 15k bulb so is 1 actinic 1 15k or just leaveit alone it doesnt make a diffrence?
