Thought I'd update a bit and elaborate on how the actual system will be set up. The display tank will be utilizing two acrylic overflows. One overflow will go to my chambered sump which will house all my equipment. The other overflow will drain into a custom refugium. The sump will have a return to the main tank and the return from the fuge will run into a location in the sump such that it is beyond the skimmer and other filtration so the small critters can make it back to the display. I will be using a power compact fixture on the fuge and a regular shop light on the sump. This way I can have the added benefit of using a refugium while having it make sense (a 5-10g fuge on a 100+ gallon system is useless). Also I know that not all the water enters the skimmer as it passes, but I am running a lot of reactors on this build also. There wouldn't be enough room and the poor things would get obliterated by my filtration. I will also have larger water volume, and when all the dosers turn on they won't destroy the fuge with bursts of chemicals. Another benefit is that anything I dose will be after the skimmer, into a large chamber of water. I now have both overflows plumbed. I can use the extra space to house new fish, so they can get used to the water before their neighbors! I just have to decide what I want to put the fuge on, no way is there room under the stand, I was thinking of stealing Dennis' cinder blocks idea. Looking for suggestions!
