I have a 30 gal
tank and am using the All-Glass triple tube lights. The light (s) still have the original bulbs in them which are 1 1/2 years old. From what I have read the bulbs will "wear out" over time. I was going to order new replacement bulbs but there is so many choices that I don't know which type/color/k
rating,etc. They are t-8 30 watt bulbs. I have fish, live rock, and xenia in my tank. Since I will be replacing 3 bulbs should I mix the k
ratings up, go with the brightest on all 3 or what? I think all the choices is whats making it confusing for me!
