Water circulation for 29 gallon biocube??

[eveningstar15]

I want to add more circulation to my 29 gallon biocube. I am debating between the hydor koralia nano 240 or the hydor koralia 425. Im not sure if the 425 would be to strong and blow my sand everywhere. Anyone have any experience with wither of these?

I had a 240gph on my 14g bc, i would say a 425 would be just fine.

I'd personally go with the nano (or 2 of the nanos) just because their footprint is so much smaller.
