Superfish CORNERFLOW 200 FILTER WHITE

An internal filter to set in a corner, output 50 to 200 litres an hour, for tanks of up to 100 litres. White.

The colour bears on how well the filter goes out of sight. A white body suits a light background, or a tank with none and a light wall behind it; a black body is lost against a dark background.

The wrong colour points the device out instead of hiding it.

The technical properties are those of the black model: 3.5 watts, a fine intake grid to guard shrimp and small fish, and room for a heater bought separately.

The Crystal Clear cassette is changed every one to two months.
