Pretty good and simple design. Would be even better if he used clear PVC so you can see inside... though it would probably cost more.

Do you think we can use this 3-ball reactor (supposed for internal use) in place of the PVC pipe version?


All we need to do is to seal up the joints tight. Advantage is that we can see what's going on inside. Only worry is if this reactor knocks on something hard, it may crack.
