Fish tank vacuum cleaner

thingiverse

This is a straightforward fish tank vacuum cleaner head designed to efficiently collect fish waste from rocky surfaces during water changes. To create this head, I envisioned attaching it to a drill pump via a half-inch internal vinyl tube. As I drain the tank for its weekly maintenance, I gently push the head against the rocks and use the suction power to clean them thoroughly, ensuring that all debris is removed rather than just taking the cleaner top water layer.
