Here are a few pics of my "behind the scenes"
Fuge: The drain line is coming from the left and dumps at the right rear of the Fuge. I drilled this (20g) tank for the water to flow out the left side and into the start of my sumps.
Start of Sumps: You can see the drain from the fuge dump into the first sump. At the rear of this sump is the drain coming from my 55g Frag tank This is connected to another sump to the left which has LR
and my frag plugs as well as a Reactor that I use as needed. Right now it has carbon in it. I keep my heaters in this fuge as well. The pump you see is the return pump for my 55g Frag tank. This sump connects in the back to a rubbermaide tote that has my skimmer and the return pumps for the main reef.
Final Sump: this is the largest of the three holding a max of 30g. This sump has a heater in it as well as the float switch for my ATO and the skimmer. I also have the return pumps for the reef in this sump. A lot of this will be changed in the up coming weeks as I finish the upgrade to the 150. I'm going get rid of all these return pumps and go with one large pump.
I hope that helps you out some. Oh and BTW...I don't normally have all those wires and things going everywhere. I have a 90g pond sitting right outside the door of my tiny fish room that has pumps going to it for the 150 build. LOL
