I want to use 1/2" PVC Pipe like bio balls. I'm designing a filter for it. I would roughen the outside & inside with Sand paper or wire brush. Then cut the pipe into 1/2" or 3/4" pieces, then glue them together in the shape of a honeycomb. Then fit them in a 4" PVC Pipe. There will be spacers in between them for water flow. The reason for the honeycomb shape is so I can take out sections and rinse them in the dishwasher for cleaning.
