currently on my 30 gallon tank I have a 24 inch, 20 watt bulb that came with the tank, hood, lighting strip etc. Do I need any extra equiptment (ballasts etc) to switch to a VHO 6000k 75 watt bulb? I never really understood all of that stuff. If I cannot use that, what would you recommend? ( I don't have live plants)
thanks!
thanks!
