Which Koralia ?

[Christian Walker]

I have a 270L tank that has a central weir from which filtered water returns. The issue I can see is that most of the flow is only on one side so Im looking at putting a koralia on the other to keep the water moving more. Its a low tech setup at present but I may upgrade. I have a feeling that a nano 900 would not be enough and would need a 1600. What are your thoughts ?

Thanks.

I would go with the1600. There is not much downside to having a higher turnover.

I just replaced a 900 and a 1600 in my 280l with a Tunze nano stream.
The difference is amazing, I'd highly recommend this as an option.
