Hello,
Curious but what does everyone run for refugium Lighting in sump?
I run a basic led light made for refugs. It less than $40 and grows caulerpa and cheato with no problem. Not sure why people pay $100s for a fug. light
My cousin has this same light over fuge and it’s very very efficient.I have this one. Works great. I have it over one section of my 40B sump.
