well the tank sits on the other side of the wall that you see behing all the equipment. the water drains in the into the sump from the overflows, one overflow feeds a 1 gallon bucket that the skimmer feed pump and CA reactor effluent drip sits in. all the water from that bucket is sent through the skimmer which drains into the sump that it sits in. i sized the skimmer feed pump accordingly with the size of skimmer i have and then fed the feed pump bucket with the same amount of water, so half of all the water that is skimmed from the display goes through the skimmer. the other overflow dumps into the far side of the sump where the phosphate reactor sits. all the water then goes to the return pump which is T'd off to feed the CA reactor and also to feed the frag tank. the frag tank overflows back into the skimmer feed pump bucket.
i am very happy with how everything is working, i might build a larger skimmer so i can process more water through it and use both overflows to feed it, but i just built the one i have so i miht have to wait a month or so.
my goal was to have all the water that overflows the display go through the skimmer and other equipment without having a ton of water just dumping into the sump un processed. i feel i have succeeded nicely since i only have about 20% of the overflow water being unfiltered
