What kind of light do I need for a refugium?
Red, magenta, and blue light spectrums are the main colors of refugium lighting. The spectrum characteristics of refugium lights give a simulation of photosynthesis and lead to rapid growth.
How many hours of light does a refugium need?
If they get at least ten or twelve hours of intense light per day, the refugia will work. Some aquarists use their lights for 24 hours a day.
Can I leave my refugium light on 24 hours?
A dark period on your fuge is what you want. Chaeto and most macros will do better when there is no light. Caloupera is the only macro that should be lit at all times. This makes it less likely that it will go sexual.
How many hours of light do you need for Chaeto?
Chaeto needs at least 8 hours of darkness so the reactor needs no more than 16 hours to work. Keeping the system water pH stable is accomplished by running a reverse daylight cycle. Slowly ramping up the light cycle over a week is what Chaeto should be doing. Start at a minimum of 4 hours.
