It's my intention to gain a new ability every 2 months for the next 20 years. I'd enjoy some company, some help, and some constructive criticism.

Aquaponics - Easy automatic duckweed feeder
Sorry folks, just a quick proof of ID.
Hi BYAP.
Actually I do have something to post though.
I had another idea for an automatic duckweed dispenser, and it works!
The previous one looked like this...
Or this from the side...
In this new easy one, all you need to do is pump some water into a pond a that's a bit higher than your fish tank, then create a flat spillway that falls into your fish tank. Make the spillway quite broad so the outflow is slow (or have a low flow to the duckweed growing tank). The idea is to not have the duckweed all flow out. A good way to do this is to create some texture on the flat spillway. paint on some silicon mixed with some fine gravel or something.
It's a good idea to add water to the duckweed pond so that the water swirls. This way the duckweed builds up in the middle, and less will flow out at each time it triggers.
If the flow and texture is correct, the duckweed wont flow over because it gets a bit stuck on the spillway.
After a while, the duckweed grows thick enough that it blocks some of the water. In my little decorative system, I get a rise in tide of around six or seven millimeters before the pressure builds up enough and dumps about ten percent of the duckweed into the fish tank.
It wont dump again until the duckweed has grown back.
The result of this is that you never run out of duckweed, you feed more duckweed in the summer (when duckweed is growing faster, and your fish want more food) and it's automatic.
Not a lot of posts for ages. but I'm still doing stuff.
