TERAPUMP Compact Aquarium Gravel Cleaner

A handy compact cleaner for nano tanks. The small, battery-powered vac lifts debris off the substrate without draining the tank, the low flow is gentle enough not to blast a nano scape, and it is easy to steer in a tight tank. Nano keepers like being able to spot-clean detritus quickly between water changes without a big siphon flooding a bucket.

How this guide was made: I don't own every product I write about, and I won't pretend otherwise. Unlike the hands-on reviews elsewhere on this site, this is a research pick, synthesized from nano and planted aquarium communities, and verified buyer reviews. It reflects the community's consensus, not my own testing. See how we research our picks →

In a nano tank a full-size gravel siphon empties half the water in seconds and a powerful vac sucks up substrate, plants, and even shrimp. Nano keepers want a small, gentle cleaner that lifts detritus off the substrate with control. A compact vacuum or a mini siphon is the right tool for a small tank.

What should you look for in gravel cleaner for a nano tank?

A few things separate a good gravel cleaner for a nano tank from a frustrating one: small and gentle, right size for a nano, control, and hover over shrimp tanks. Weigh these before you buy.

Small and gentle: low flow that will not vacuum up substrate, plants, or shrimp.
Right size for a nano: a mini siphon or compact vac, not a full-size washer.
Control: easy to steer and stop in a small tank.
Hover over shrimp tanks: skim detritus off the top rather than deep-digging the bed.
