Once this set up installed and functional as is the next part of the set up will include a secondary settling tank for next Spring and this one WILL have a stirring mechanism as it will be "outside the box", so-to-speak :) so head space will not be a concern and I can set up an inverted drill press on a stand or whatever with an extended paint stirrer or other makeshift apparatus that will give it the heave ho, but for now I have to make this present system functional without bubbling and this "rain" thing seems to be the only way to do it. given the space available to work with. Like I said, it does work, howbeit not as well as I would like, and so I am dogedly staying the course until I discover something that does work perfectly well for the application. Sticktoitivenes and perseverance are not things I lack, although they can also be a fault :) if blind.
