questions about oceanic 29gal bio cube.

[JSTR]

You have a few options with nanos.

1. You can go skimmerless, but you must do weekly water changes to export the nutrients.

2. Custom skimmer to fit in. (nice fit - but expensive)
eg: http://www.nanotuners.com/product_in...roducts_id=358

3. Cut the canopy to accept a small skimmer like the remora aqua c.

4. Drill holes and run a external sump.

Each has its upside and downside. Nanos are interesting that way. Check out
