I currently am running a 40 gallon reef with a 20 gallon sump.... I have variety of mushrooms and polyps.... Im currently using a USHIO 175W 10000k bulb... Problem here is that i want my shrooms and polyps to show there vibrant colors.... I understand i need actinics to fullfill this, soo could i just buy a new 175w 20000k bulb and get the effect im looking for or do i have to grab a whole new ballast? Money is kinda tight on a college salery. lol...
Thanks Guys.....
