So, with the upcoming upgrade, I wanted to take the opportunity to upgrade my return line and add some tees, so I can hook up a UV, GFO, and a couple to grow on. Is there a good design out there that is easy to plumb and use and maintain? Am I looking for a holy grail? I've been searching for days now and there are so many different styles, that I end up confusing myself. Here is the room I have to work with. I got a smoking deal on a waveline dc5000, so that's going to be the new pump. Here's a shot of my sump room. I would love for this to look as good as it works too... The black line is my return, the clear towards the top is the UV, no GFO shown. I found this website that has much much more than menards/HD/Lowes has on their shelves. http://flexpvc.com/ Thanks!
