I have the link and downloaded the PDF manual. I thought I should not link unless asked. Its made to be attached to the top rail of an AG pool. No plumbing just stick it down in the water.

Looks middle of the road price wise about 400$. I was considering maybe as a start up IDK just throwing it out there to see if it floats.

It seems all of the other ones involve some type of plumbing. So it makes me wonder.
