I plan on running biopellets and am using an ETSS1400 w/250ps Panworld for my 240g (400g total volume) system. I would like to run another large, but in sump skimmer, but don't have a clue what's state of the art (for under $1000) these days. I really wouldn't mind retiring the 1400 if I can find a powerful enough skimmer that uses 200watts or less. That's half of the Panworld.
I plan on having a large number of fish, with just softies and anemones, but don't want the algae associated with heavy feedings.
What do you guys with large systems run? Also, am I putting too much importance on the skimmer and is there something else that large systems use for nutrient export (besides biopellets)?
Last, does everybody run a refugium or sump with tons of algae or mangrove forests? Is this a necessity?
