It would be stupid labor intensive and a real mess! Enter FloweRock Quarter Lava Rock. Sure, its more expensive then going down to the hardware and buying bbq lava rock, but holy gods, how easy is it to rinse and go, just like any other high priced aquarium filter media? One little ding, there was a ton of grit to rinse out. I'm still washing out my wash out bucket as I write this. But seriously, the more biomedia the better for my dirty ol' oscar Pumpkin. This size was tough to find locally, so I was very pleased. Thank you!
