Review: Great compact low flow quiet filter - 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.
Review: VERY POOR - for this premium brand it is a poor filter!!!! ISSUES- suckers pull off every time you clean it and are awkward to put back in place because they foul against the inner filter trays -filter flow is very poor mainly down to the design of the pull off motor head flow escapes from the rear around the joints - inner tray is flimsy and i can not see the joints lasting long (in my opinion ) a real shame as it is a nice looking compact unit !!!!

## Questions & Answers

**Q: Can you buy replacement filter media**
A: Sorry - don't know - Oase is a good established brand so if anyone does, they will - I bought mine for 2 messy turtles but the pump just wasn't up to the job.

**Q: Is this filter ok for musk turtles ?**
A: This one would not be up to the job. I suggest looking at the Fluval range of filters.

**Q: Can you remove the carbon granules?**
A: Yes, the sponges and granules both come out in little cartridges - like a mini Fluval. They are actually very good for their size and price. I've had one going for about 6 months now. Very reliable little things. The only downside is getting the suction cups on it - but maybe that's just a technique I haven't got!

**Q: is this ok for betta**
A: Yes it should be

### ⭐⭐⭐⭐⭐ Excellent little filter that deserves more reviews
*by A***D on 3 November 2019*

This is a great little filter for a small tank. I have them working in my small 25L tanks. Decent flow and uptake considering how small they are. They first appear small, cheap, and a bit crappy, but give them a chance. The sponges and granules both come out in little cartridges - like a mini Fluval. These filters are very good for their size and price. I've had one going for about 6 months now. Very reliable little things. The only downside is getting the suction cups on it - but maybe that's just a technique I haven't got!
