Modern Plastics is in Shelton, Acrylic factory is in Bridgeprt, the owners of each are brothers. I personally go to Modern Plastics, I stop in just to see whats in the scrap bins even if I dont need anything, and Raul always hooks me up. I got all the acrylic for Mason (masedaddy) and built his sump with him, and have pointed several other members in their direction. They have all the weld-on levels, applicatiors and lots of other acrylic working supplies.
If your creative your brain will go wild with all the different size color and shapes of acrylic they have. I snagged a bunch of different diameter tubes last time I was there, gonna play with making a skimmer or reactor, just for fun lol
