A Herbie in principle is the same for a 400g or a 20g it's just a matter of size of bulkhead.
With the Hydor's doesn't sound like you'll be needing to rely too much on water through the sump to supply the flow for your display. Meaning either a Herbie using small bulkheads or a Durso.
What size of flow you planning from your sump?
