So I have a refugium in my sump. I bought the macro grow light for it at the time it's a 25w CP bulb. I've been running the light on it when my main lights go off up top.
I also have added a PAR38 36w LED
fixture that I couldn't use on my Pico build.
Should I run both lights only at night or during the day as well? The macro algae I have hasn't grown or anything in over a few weeks. I only have calupeura and chaeto right now in there. I'm open to suggestions for more /different macros.
I was growing mangroves but they had a hard time since they were so short so I moved the mangroves into my biocube.
So in short
When do I run the refugium lights?
Can/should I add more macro algae?
Are two lights overkill?
If two light fixtures are bad which one do I remove?
And any suggestions or comments are welcome as usual!!
Thanks for the help guys, Mucho appreciated!!
