As promised, I'm submitting for approval to all my 3reef reviewers, the build involved in replacing my skimmer. The skimmer was the only thing to be replaced, really. After some thought, I figured it wise to get rid of the powerhead that's feeding my chiller. Powerheads IMO are best kept for tasks for which there is easy access. For my chiller build, I kinda "winged" it, and used a PH I had laying around. So, with the removal of the feed to the chiller came the need for a new return pump, to act as both return, and feed to the chiller--and later it dawned on me that I might as well feed my reactor as well, and keep a port open for future use. So here's the progress thus far; now that the sump (a 20 gallon long) has been drilled and most all parts are here. First, here is my tricked out filter sock holder. The acrylic is nearly thicker than my 90G DT. It came with 2 socks, so I couldn't pass it up. The pump is an Iwaki MD40RLXT, a 1340 GPH pump that's fairly quiet. Thanks to Otty for the link to these guys who sell PVC manifolds. To me, they're made for us reefers. This is a 1 1/2" in, with 4-1" outs. I'm using it with a reducer to spin onto the pump's 1" male output. Here's a shot of the manifold as it's going to be, with two-1" feeds, one for the tank return, and one for the chiller. The other two are capped off with teflon tape so I can use them in the future. . . and here it sits on the pump. Another shot: Got the sump back from the mirror decor place that does a lot of work with glass, and drills holes and cuts baffles for dirt cheap. Here's the sump with holes for the return pump, the chiller return, and the float valve for the ATO. Some bulkheads in place. .. I attached the pump for measurement purposes. I'm trying something a bit different, I'm going to mount the gate valve for the return pump inside the sump, since I can't afford the length on my stand. It's made entirely of plastic, and the handle clears the aquarium's wall, so I'm not anticipating any problems. I'll snap some pics of that once I get the close nipple to make it happen. For now, I'm putting a bubble trap to separate the skimmer portion of the sump from the return portion. The first piece of glass will maintain the level at 8 inches even--although Patrick (tatted4ever) stated that this skimmer likes 6". I'll put the skimmer up on some sort of pedestal if it has to be raised. I'm more comfortable having the water depth and not needing it; than needing it and being, well, up the crik, as it were. Anyone who saw my "Creation Of The Fuge" thread has seen pics like these before. My parents always told me that books are very useful. They were right! First I get the height right, and mark the outside walls with a sharpie. Then I run a bead on that line, replace the glass, and run another bead above the glass. This method keeps everything level, neat, and rock solid while things dry. OK. This will sit for at least 8 hours while I gather up a few more pieces. Stay tuned!
