Rank #5 in Best Aquarium Filter 2026: Turnover Is the Only Number
NICREW Magi200 Fish Tank Filter, 200 L/H for 20-40L Tanks
Price and rating as shown on Amazon when we collected them. Both change.
The NICREW Magi200 is rated at 200 litres an hour for tanks of 20 to 40 litres, which is five to ten turnovers an hour, for £15.99 with 2,940 ratings at 4.3 stars.
It takes fifth because the sample sits behind the two filters above it, and first on arithmetic: it is the only filter here whose published flow and published tank range both match the four-to-six turnover rule, at the top of its tank size.
How those 2,940 ratings break down
An average hides its own shape. This is the spread behind the 4.3 stars.
