Well, the day has finally come to start a build thread on my 150g reef project. This will be my first "large" system, as I currently only have an IM10 reef tank...so this is quite the jump in size....which obviously means quite the jump in planning, time, and money. It's been just about a year since I purchased the primary equipment (ie. Tank, sump, return pump) and have picked things up along the way as well. I also have yet to buy some small pieces of equipment as well (ie. Powerheads, ato..) but primarily I have all the equipment to get it started. Equipment list.. 150g high DT (drilled rear back left corner) Eshoppes eclipse L overflow Trigger Emerald 34 sump Eflux return pump Red sea c-skim1800 skimmer Triton pump to feed skimmer Radeon xr30 (x2) Heaters (x3) Plumbing materials Now...I started with setting the plumbing up before I did anything else. After buying the skimmer, I realized that it was going to be slightly more complex to plumb, since the skimmer is MASSIVE and would not fit well enough in the sump chamber. I was going to have to run it externally, and feed it from a separate pump within the sump. When I made enough room in the stand for the skimmer alongside the sump as opposed to IN the sump, this created an issue with the back brace of the stand, being smack in the middle of where the overflow plumbing would drain into the sump. I was going to have to get creative. So the plumbing is a combination of both rigid sch.40 and flexible tubing.
