One of the pics in a previous post shows a ton of fittings and valves. Most of them will be used. I plan to build a manifold off of the return to allow me to easily add reactors for carbon, gfo, and or bio pellets. It will also have a valve for quick and easy water changes between tank cleanings. It will make more sense as it comes together.
