Floating HOB Filter Plant Separator Surface Guard

Floating HOB Filter Plant Separator / Surface Floater Guard This 3D model is a floating ring-style separator designed to sit around the outflow of a hang-on-back (HOB) aquarium filter. Its purpose is to keep floating plants like frogbit, red root floaters, salvinia, duckweed, and similar surface plants away from the filter current and waterfall zone. If you keep floating plants, you already know the problem: they drift into the filter flow, get pushed under, stay too wet, or collect in one messy clump. This separator creates a clear open area around the filter output so water can move freely while your floating plants stay outside the high-flow section of the tank. What it does Keeps floating plants away from the HOB filter outflow Protects floaters from being constantly shoved underwater Maintains an open area for surface agitation and gas exchange Helps keep the tank surface looking cleaner and more organized Works well in planted tanks with floating plants Good for plants like Frogb
