I currently looking to build a sort of hybrid tank system where the tank water goes up and out through one or two 36" flower pots before going into the sump which I will be making also. The flower pots will be planted with typical house plants in gravel on a flood and drain bell siphon system such as this one http://www.youtube.com/watch?v=BzKUzcdeaI8&feature=related. My big issue is buying the pvc piping in the sizes needed since I would need three different sizes I havent found anyplace near me that is willing to sell me the sizes i need in one to two feet quantity that I need. Everywhere they sell I believe either 8ft or 10ft of pvc which is way much more than I need. So does anyone have any ideas as to where to get about 2ft of pvc in the sizes I need? I'm located in Manhattan, NY and live in an apartment so having 3, 6ft pvc pipes laying around that I may never need won't sit well with the wife. thanks in advance. Here's a video of constructing the bell siphon http://www.youtube.com/watch?v=vXaPn6SjvxU&feature=related
