refugium plants

[jc]

I have this fuge that I added to my 180 to try to get the nitrates below 15 in my fowlr tank. As you can see the cheato floats over to one side. I was wondering is there anything else I can add to the fuge to help such as calupera. I can run the fuge light 24hrs if need be. Does calupera grow fast? Any other recommendations?

You can add calurpa if you run the lights 24hr, if not it will go sexual and really mess up your tank.
IMO, I would just stick with chaeto, maybe mangroves or drangons breath

The cheato will completely fill up that area. I have some ugly live rock in all my fuges. I dont know if it helps much, however, I do have an abundance of diverse life forms in my fuges.
