Rank #6 in Best Aquarium Filter 2026: Turnover Is the Only Number
Harune 1200 L/H Internal Aquarium Filter with 10W UV Light
Price and rating as shown on Amazon when we collected them. Both change.
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.
How those 19 ratings break down
An average hides its own shape. This is the spread behind the 5.0 stars.

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.
