I have made a little progress.
Proskim -
at least in one video - show the whole process.
This page shows the whole kit. Although the price is much the same, at least it's all-inclusive, aside from the shipping to NZ cost. For the other option I mentioned earlier, the price was just for the floating skimmer part.
The apparent depth of the floating skimmer could be a concern. My pond is only knee deep.
One other potential problem is there are two screens: one for watermeal and one for duckweed. I have both weeds!
