Where did you eventually place it? How old was your tank when you the refugium installed? I’m hovering around the 2.5-5 ppm nitrate and .02 Phosphate. Just looking at doing something similar and install it in section 5 of your diagram in the bottom of an intank media basket.Yes, thank you. I took it down. Although the Chaetomorpha did not die, it did not grow either. I decided my system was too young and the nutrients too low (I usually hover around 1-2 ppm Nitrate and <0.05 ppm Phosphate). I did grow a lot of hard to scrape green film algae on the acrylic and glass panes in the chamber and Cyanobacteria over the Chaetomorpha. That nuisance ultimately made me decide to give it up for now.
I did leave my grow light in place, so as my system matures, livestock is added and nutrients rise, I may try again.
