I already replied on your blog regarding this video, but OMG THAT GROWTH IS INSANE!! You should be referred to as the Chaeto Master now. I've seen this same chaeto tumbling system in place on a few systems before, all with fantastic results (granted you must have an efficient light source, get the tumbling right, and have nutrients available in your tank for the chaeto to thrive on). Really it seems like a very easy to setup and manage way of filtration that can be extremely effective. I'm excited to try this on my own setup. I don't have the room in my stand so it will have to go next to the tank but it actually looks pretty cool and mesmerizing like you said, and would be pretty fun to watch all the pods and micro life in there. A few questions: what is your light cycle for the chaeto fuge (on all day, at night, etc.)? What flow rate do you run, or how would you suggest dialing in the correct flow rate (i suppose it really depends on the tank dimensions and size if chaeto ball)? And what do you do with all of that extra chaeto you pull out and the pods/micro life within? Thanks, and again, very cool!
