Feather Dusters...Bioload hazard?


Reefing newb
So I was considering adding a Featherduster Worm to my tank, but was wondering if they added to the bioload. Right now everything in the tank is perfect, except for a slightly elevated Nitrate level (which may be because my turbo snails eat the algae too quick).

Also, pros/cons of featherdusters? Any thoughts really.

Thanks! :D
No, they do not add to the bio load. Pros--- they are cool creatures, add a different element to the tank, filter feeders. Cons---- none I can think of off the top of my head.
