That is an AWESOME idea!!! I bet it is easy to change/clean. you don't have to take the whole thing apart.
It is very user friendly. Mostly only have to clean the top two filter floss pad trays. I also ran a tray with phosban and a tray with charcoal. Lots of flexibility and very easy to swap things out.
The inch of head in the water bottle flows into the sump and that's about it. No siphon to bring the water to the sump, just gravity.
How does it start back up after the power is restored?
Here's the (very French) passive kalk doser that I use on my ATO. It's a Perrier bottle, rigid airline tubing is epoxied into the top and bottom holes. It just needs a jiggle every so often to prevent any channeling of water through the kalk, athough that's mostly prevented by the kalk powder settling and concentrating in the neck. You can see a nice little cloud of kalk form as the water flows up through it. It performs great, maybe even well enough to say it's ghetto fabulous.

if you cable-tied an electric toothbrush (or ahem...wink!) to that, it would vibrate itself and not need shaking manually. work out a way to rig it up to the mains, and you could easily have a true ghetto-winner!
How do you control the exact amount of the dosing?Here is my ghetto doser.....
