That is problematic in the use case as I plan to be asleep when it is running.

I think the flow rate will be alright since it only needs to provide enough of a current to keep all the water moving. A half barel keg is 23" high, and that is what I used for my heating vessel, so the head height is not an issue.

I sort of wish I had gone with the 12V version, but I already had a 5V AC adapter in my box of electronics junk. If the 5/6V version does not work in the end, I will turn it into something cute for my kids to play with, or a sous-vide, since I have never had salmonella before.

Here is what the setup looks like for the curious. I don't plan on using that vinyl tubing connecting the hose barb to the pump. I am waiting on silicone tubing to arrive.

I will go a full scale test when the tubing arrives. If it does not work I will have to get a better pump or an agitator. And then someone else can learn from my mistake, so it is a win either way!
