I used Rox08 only for years - very high quality and usage was minimal (i.e. need less carbon in system for affect). I recently picked up a 5 gallon bucket of the bituminos carbon and really liked using less carbon...lol. I swap mine out every two weeks (4 - 6 cups for 330 gallons). Too much rinsing, dusty mess. As for the lignite, haven't tried it I will likely move back to the Rox08 though. It is so clean, rinsing it may not even be necessary.
Have fun!
