Need advice for filtration options for Bio-cube 29

I have the Coralife 29 and I'm looking for a good mechanical filter, probably a power filter, as I would like to get the water cleared up and I'm not sure the Coralife return pump really cycles enough water.

I would also like a better skimmer. Again, I have the coralife skimmer that fits in the first chamber and it is just tiny and ineffective.

Does anyone know of any good HOB filters that will fit on this Bio-cube?

Thanks.
