Hi bros, I figured since most of you are using overflow systems you could help me in solving my problem. I bought a chiller a few days back from my friend for my 3x2x2 tank. It came with pipes for the inflow and outflow. However, the pipes are too big to fit the pipes that I'm currently using for my filtration system. Is there any way to solve this problem? Are there some kinds of pipe fittings that allow me to connect a smaller pipe to a larger pipe?
