Yes and No.
It will work as a water circulator/waterfall.
However it is just a pump from what i could find. so any filtering action will have to use something else.
My filter is "needed" because i don't want to change the water every 2-3 days. With the filter i change the water/clean once a week. Those brine shrimp really dirty up a tank if you don't have some sort of filter. And i dont' have to change all of the water.
I know some people have kept FBNs in tank w/o filters or water circulation but they need to change the water every other day it seems. I think that would be a really poor setup.
