The Harune is a 1,200 L/H internal filter with a 10-watt UV steriliser and a timer, for tanks it describes as 100 to 400 litres, at £32.99 with a perfect five stars from 19 ratings.

It takes sixth because the claims run ahead of the evidence: 19 ratings, a claimed range spanning twelve turnovers an hour to three, and a price above filters with twenty times its reviews.

## Questions people ask

**What tank size does it suit?**

In practice 200 to 300 litres, where 1,200 L/H is four to six turnovers. At 100 litres it is twelve, and at 400 litres three.

**Does the UV light work?**

UV sterilisation is a real treatment for green water; a 10W tube with a visible window is the practical arrangement.

**Why only 19 reviews?**

It is a newer listing, so the perfect rating is unproven — treat it as promising rather than established.

**Is it for a large tank?**

Yes: it is the biggest flow here, designed for heavy stocking.

**Why is it sixth?**

Because 19 ratings cannot justify a position above filters with thousands.

**How many ratings does it have?**

19 at the time of collection, averaging 5 stars, with 100 per cent five-star.
