how many times a hour should the water go through the sump?

Ok, if you read that it is not an efficiency, it is how much it will remove in 24 hours.. an eficiency would be how much it would remove in one volume change of the skimmer, which is what this discussion is about having a flow rate matched to your skimmer. so if my skimmer had a flow rate of 600gph, I would call the efficiency the amount of crap removed from 10gal of water in 1 min, a power efficiency would be how much is removed compared to the power input.

so ya the 80 and 20%s have nothing to do with what we are talking about really.

So how would you rate the efficiency of the following example...

You have a protein skimmer that requires a 600 GPH feed. You feed said skimmer 600 gallons of display tank water every hour with no bypass in the sump and without allowing the skimmer to process water twice before it is returned to the display tank.

No one in this thread claimed that is 100% efficacy, but since you are broaching the subject, how efficient do you consider that configuration to be?

The thread isn't about protein skimmer limitations. It's about making the operation of the equipment you have run efficiently.

That scenario will be as efficient as the Skimmer manufactures designed it to be.
