## Customer Reviews

### ⭐⭐⭐⭐⭐ Great compact low flow quiet filter
*by E***A on 19 February 2025*

I wanted a low flow filter for my fish tank which is a cubic 30x30x30 (cm).With this filter you can adjust the flow which is perfect for small fish and ideal for my betta fish.You can direct the flow in different directions with the added attachment and the filtration has been perfect for my tank, keeps it nice and clean in between water changes and when re-arranging my live plants.This filter is also very quiet which is perfect as the tank is situated in a bedroom.I would be careful when the handling of the filter, but it’s fine for me i just delicately wash the parts.Overall, impressed with this little filter.

### ⭐⭐⭐⭐⭐ Ideal filter for a small tank
*by R***K on 1 January 2020*

Small, works well although having had it for a while now, I have noticed the pump leaks from the sides. Still works okay though.

### ⭐ Bad
*by V***F on 14 April 2023*
