Normal ATS vs UAS vs Floating scrubber?

[nanomania]

Hey guys, i would like to know which one works the best. Anyone using them as a sole filteration system? However im not much intrested in the floating one as it takes a lot of space, but if that works the best then good. Do they really work? Also iv read that they can crash the tank if not cleaned weekly. Iv seen 100z of videos but most of them use a skimmer along with it, but the websites claim they can be used as a sole filter for the tank, which i doubt a bit, just like many other manufacturers who claim to be tha their product is the best, etc. Etc. Also how is growing macro algae different than growing hair algae in ats.?
