Bubble Magus Mini Q vs QQ2

Researched by Johnny Alto · last updated July 27, 2026

Short answer: For most buyers, the Bubble Magus QQ2 is the better pick over the Bubble Magus Mini Q. For anyone running a sump, the QQ2 is the pick.

Top pick

Bubble Magus QQ2

For anyone running a sump, the QQ2 is the pick. It uses the same needle-wheel pump and carries the same nano rating as the Mini Q, so it skims just as well, but its slim in-sump footprint tucks into a tight sump chamber. Reef keepers with a sump reach for it because it is the same skimmer in the body shape their setup needs.

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 reef communities like Reef2Reef, and verified buyer reviews. It reflects the community's consensus, not my own testing. See how we research our picks →

Both are budget nano protein skimmers rated for around the same tank size, and they use the same pump, so this is not really a performance contest. The real difference is how you mount it: the QQ2 is a slim in-sump body, the Mini Q (QQ1) is a hang-on-back unit. Here is how to choose.

Bubble Magus QQ2 vs Bubble Magus Mini Q: what is the difference?

Pick	Product	Why it makes the list
Top pick	Bubble Magus QQ2	For anyone running a sump, the QQ2 is the pick.
Hang-on-back	Bubble Magus Mini Q	Pick the Mini Q (QQ1) if you do not run a sump and want a true hang-on-back skimmer. It performs the same as the QQ2 (same pump, same rating); the only real difference is the HOB mount versus the QQ2's in-sump body, so choose by your setup, not by skimming power.

Which one should you buy?

The two are close, so the choice comes down to a few things: mounting, performance is a wash, footprint, and water depth. Here is how they split.

Mounting: QQ2 sits in a sump; the Mini Q hangs on the back.
Performance is a wash: same pump, same nano rating, so do not choose on skimming power.
Footprint: the QQ2 is slim for tight sump chambers.
Water depth: the in-sump QQ2 needs a few inches of water to sit in.
