The mini submersible filter costs £10.97 with 4.3 stars from 35 ratings: 200 litres an hour, 3 watts, two outlet types, and a stated tank range of 3 to 40 litres.

It takes eighth because the range is so wide it cannot be honest at both ends — 66 turnovers in a 3-litre tank, five in a 40-litre one — and because 35 ratings, while holding fifth place in the category, is thin evidence.

## Questions people ask

**What tank size is it for?**

It claims 3 to 40 litres, which is a thirteen-fold range: at 40 litres it gives five turnovers an hour, at 3 litres sixty-six.

**Is it noisy?**

One reviewer finds it loud until lowered slightly; the pump is small and sits inside the tank.

**What are the two outlets for?**

A spray pipe for surface agitation and a standard outlet for circulation.

**Is it suitable for shrimp?**

Yes, at the small end of its range with the flow reduced.

**Why is it eighth?**

Because the evidence is thin and the claimed range is implausible at one end.

**How many ratings does it have?**

35 at the time of collection, averaging 4.3 stars, with 73 per cent five-star and 10 per cent one-star.
