Hate it! It is supposed to use suction to draw water into the reactor and eliminate the need for a peristaltic pump. However, the effluent rate always slows down over the coarse of a few days, drop almost comes to a stop, and I have to manually readjust.
Roger at Tunze has been a great help, but after about 20 emails back and forth and constant tweaking. I’m about to throw this thing in the garbage and go with the proven peristaltic/Geo route.
ouch, that sounds painful. Can you simply add a peristaltic pump?
