Tiny internal power filter

[Aderynglas]

Today I bought the most amazing tiny internal power filter for my smallest tank (14 litres) its a Dophin KF-150 and measures just 8 x 2.7 x 4 cms and has an adjustable flow up to 150L per hour

Has anyone got any experience of this make? I've never heard of it in UK before and am hoping it works well.

KF-150 Filter

Hi

I just bought the same filter. Small and silent. My problem thought: Is it suppose to suck air through the pipe on top (Venturi)? Mine doesn't and I want it to. Can anyone please help me?
