I have a dual bulb strip. One bulb is a Coralife 50/50 6000K/Actinic 03
. The readings on it says F20 T12 360 BP. The other is a blue bulb with a metal casing on the one side. The bulbs have not been changed in quite a while.
1. How often do you change bulbs?
2. Can anyone tell me how many watts the 50/50 bulb is?
3. What type of bulb is the blue bulb I described? I cannot find any description on the bulb?
4. Will this cause poor water quality?
One piece of live rock has hair algae (not much) and nitrates are 20-40ppm, which I plan on adding a skimmer after the holidays. Any help is appreciated.
