Great design, seems like it will make a strong concentrate. I make compost tea by filling a 55-gallon drum with water, manure and herbs and throw a few aerator stones in. Takes a few days and doesn't usually smell bad unless it sits for too long.
How difficult of a task is cleaning out this tube for the next batch?
Im doing a post on my air driven compost bubbler soon.
The pipe is easy to clean. The vegetable matter gets compacted at the bottom and most of the liquid in it has dripped out.
At worst, it takes a poke with a switch or a blast with a hose once the bottom cap has been removed.
