Nano-system for Christmas tree rock, bryozoans

[Reefyone]

Any suggestions on keeping filter-feeders nano-system(s). Chiristmas tree rock, bryozoans, feather dusters, pink-green sea cucumber particularly.
I mean other that they need large system and live food supply

I have a feather that I bought and a bunch of smaller hitch hickers and I don't feed them. My feather has gotten huge! They will get what they need when you feed your fish. Most filter feeders don't need extra care. You can dose liquid phyto but dont use it to much cause phosphates love the stuff too.
