Great, thanks for the offer tangster!! Let me update on what i have done. A bit of a disapoitment, but not too bad. I emptied the closet behind my fishtank, and i am going to tear down that wall and place my refugium, sump, skimmer, and the closeloop. Once i have the opening done(wich i will finish today, monday) i will purchase all the materials i need to do the re-plumbing and closeloop. And i will start with that next weekend upon getting all i need. So ill let you know tangster if i cant find flex pvc, and we will arrange something. Ima post pics of the closet in a few before i tear down the wall.
