filter set set up?

[jeepjunky]

This sound right? water fills overflow (in tank) and gravity drains into the top (dry side) of the wet/dry sump. Water then trickels over the blue bio balls and fills the wet side of the filter. while in that side it is sucked into the skimmer, then skimmed and the clean water drains back into the wet side of the filter and is pumped back into the tank?

Or dose the water leave the skimmer and head to the tank?

also how do you keep the system from failing and flooding the wet/dry filter and living room? Is that set by how deep the overflow is set into the tank?

Thanks

Also any ideas how many gph do I need for the overflow and sump back to tank pump? btw 55gal tank

A good rule is a water turnover of 10x-20x of the water volume.

I understand the 10x-20x rule. But I have 2 power heads. Just split it to thirds? Or dose the wet/dry filter and skimmer need more or less, or all?
Thanks

Since live rock should be your main filter I would do at least 20% through the sump. More would be better for the skimmer to pull as much waste out before the rock can get to it.
