Also, what a lucky find, that estate sale. And lol at the hookah ;)
Can you elaborate on how you're raising azolla/duckweed? What's the source of nutrient in the water?
I think if you put basically any kind of thing around the aerator, like a tube of window screen or even hardware cloth -- just something to help keep the disturbance localized, that might help. Also, you can get air tube metering devices for cheeeeaaap at the aquarium store. Or heck, even the right binder clip to restrict air flow might help.
Your rooster is very handsome.
Tobacco isn't my first choice of vices, but after 16 months of not being able to indulge any vices, I'm not one to complain about whatever shows up for free. And it's a nice way to meditate.
The duckweed has not been successful yet. When I checked on it this morning a lot of it was turning white, which I suspect is probably a lack of natural lighting (since I wanted it close to the chickens for easy feeding, but that ends up keeping it in the shade most of the day.) Could be a lack of nitrogen, but I don't think that's likely. Could also be a pH issue. In any event, I've completely drained the pool and I'm moving it to a spot where it'll get more natural light and I'll give it completely fresh water until I can figure out the nutrients. It's one of those things that should be impossible to kill, but I have a history of killing things that are impossible to kill, so... 🤷🏻♂️ Been trying a combination of nettle tea and urine. Could be too much salt. I'll just start with nothing and work up from there.
I haven't played around with aerating the water since that first attempt. Not sure I'll be able to now, since moving the pool to where it can get light means I won't have protection from the elements or easy access to electricity. Still want to experiment with it, but focusing on the basics first before I really try to dial in production. Gonna need a much bigger area to produce the amount I need anyway. I've been toying with the idea of using ferro-cement to create a shallow basin to grow it in. We'll see. Have also been thinking about a ferro-cement container for the black soldier flies as well. Just gotta figure out what makes the most sense as far as time, cost, placement, and materials.
